(Received 11 December 2013; published 25 April 2014)
Results are presented of a search for a “natural” supersymmetry scenario with gauge mediated symmetry breaking. It is assumed that only the supersymmetric partners of the top quark (the top squark) and the Higgs boson (Higgsino) are accessible. Events are examined in which there are two photons forming a Higgs boson candidate, and at least twob-quark jets. In 19.7 fb−1of proton-proton collision data atpffiffiffis¼ 8 TeV, recorded in the CMS experiment, no evidence of a signal is found and lower limits at the 95% confidence level are set, excluding the top squark mass below 360 to 410 GeV, depending on the Higgsino mass.

The recent measurements of the properties of the new boson with mass around 126 GeV by ATLAS [1,2] and
CMS [3,4] experiments confirm that it is consistent with
the standard model (SM) Higgs boson. One of the most important problems in particle physics is now to understand why the boson’s mass is so small compared to the Planck scale. Supersymmetry (SUSY) offers an elegant solution to this hierarchy problem. Although experimental searches have found no signs of it so far and the simplest SUSY models have become increasingly more constrained, there remain very large yet unprobed areas of SUSY parameter space that can still be “natural,” i.e., have a fairly small amount of fine tuning.
The essential requirement of natural SUSY is that the masses of the superpartners of the top quark and the Higgs bosons, the top squark and the Higgsinos, be light (see, e.g.,
[5,6]). This Letter describes a search we performed for
events with a topology motivated by SUSY with a gauge mediated SUSY breaking (GMSB) model[7–10]. Complete GMSB models are considered with a minimal number of accessible SUSY partners to satisfy the naturalness require-ments, namely, the right-handed top squark and Higgsinos. The lightest chargino (~χþ1) and neutralinos (~χ01,~χ02) in this case are almost pure Higgsinos and are therefore almost mass degenerate.
Pairs of Higgsinos are produced either directly through electroweak production or through right-handed top squark-antisquark pairs (strong production) with cas-cade decays
~tR→ b~χþ1 or ~tR → t~χ0i; (1)
where i ¼ 1, 2. The ~χþ1 (~χ02) subsequently decays into a very off-shellWþ (Z) boson and a ~χ01. (Here, and in what follows, the charge-conjugate final states are also implied.) The near mass degeneracy of the Higgsino states requires the off-shell boson decay products to be very soft.
The decay of the lightest neutralino in all cascades is ~χ0
1→ H ~G or ~χ01→ Z ~G; (2)
where ~G is the gravitino. The branching fractions of ~χ01decays depend on SUSY parameters. For a significant portion of the parameter space, neutralino decays into Higgs bosons dominate. This includes regions of low tanβ, the ratio of the vacuum expectation values of the two SUSY Higgs doublets, and negative values of the Higgsino mass termμ[11].
The final state of interest, therefore, has two Higgs bosons, some missing energy from the gravitinos escaping detection, and, in the case of strong production, two bottom (or top, if kinematically allowed) quarks from top squark decays, as shown in Fig.1. SM backgrounds, e.g., from top quark pair production, are suppressed by taking advantage of the known Higgs boson mass and by considering the case when at least one of the Higgs bosons decays into two photons and at least twob quarks are present from either Higgs or top squark decays. This approach also allows us to use diphoton mass sidebands for an estimate of the back-ground from data, without sensitivity to the exact compo-sition of the background, which is dominated by QCD production ofγγb¯b events and γb¯b þ j events with the jet being misidentified as a photon.
We use a data sample of19.7 fb−1 collected during the LHC 8 TeV running with the CMS detector, which is described in detail elsewhere[12]. The detector comprises a silicon pixel and strip tracker covering the pseudorapidity range jηj < 2.4 (where η ¼ − ln½tanðθ=2Þ and θ is the polar angle of the particle with respect to the counterclock-wise proton beam direction) and electromagnetic and had-ronic calorimeters, which cover jηj < 3.0 and jηj < 5.0, * Full author list given at the end of the article.

respectively. The tracking and calorimeter systems are housed inside a 3.8 T solenoidal magnet. Muon chambers are imbedded in the iron return yoke of the solenoid up to pseudorapidity of jηj < 2.4. Events are required to pass a suite of diphoton triggers that impose mild shower shape and isolation requirements and demand transverse energies (ET¼ E · sin θ) above 36 and 22 GeV for the leading and the subleading photon, respectively.
The signal is simulated for a grid of Higgsino and top squark masses using the MADGRAPH 5 v.1.5.4 [13] and
PYTHIA 6.4.22 [14] generators and fast simulation of the
CMS detector[15]. The next-to-leading order (NLO) cross sections (shown in Fig. 2) are calculated usingPROSPINO
2.1[16–21]. The Higgsino mass splittingsm~χ0
2− m~χþ1 and m~χþ
1 − m~χ01are set to 5 GeV, and a 100% branching fraction is assumed for the ~χ01→ H ~G decay. All other superpartners have masses too heavy to influence SUSY production at 8 TeV.
Photon candidates are reconstructed from the energy deposits in the electromagnetic calorimeter by grouping the calorimeter’s data channels into superclusters [22,23]. Photons are required to register in the barrel portion of the calorimeter (jηj < 1.4442) and to pass shower shape and isolation requirements. To reject electrons misidenti-fied as photons, photons are also required not to have associated hit patterns in the pixel detector consistent with a track. Photon energies are calculated using multivariate regression[4,23].
The particle-flow (PF) algorithm[24] is used to recon-struct individual particles (PF candidates) in the events,
combining all available subdetector information in a coherent and optimal manner. Jets are reconstructed from the PF particles using the anti-kT [25] algorithm with a
distance parameter of 0.5 and are required not to overlap with the two leading photons by imposing a requirement ΔR > 0.6, where ΔR ¼pffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiffiðΔϕÞ2þ ðΔηÞ2 and ϕ is the
azimuthal angle. Transverse momentum andη-dependent corrections to the jet energies are applied to account for residual effects of nonuniform detector response. The pileup contribution is estimated and subtracted from the jet energy using the jet area method[26]on an event-by-event basis. The combined secondary vertex (CSV) algo-rithm[27]is employed to identify jets that originate from a bottom quark.
The missing transverse energy (MeV) of the event is computed as the magnitude of the vectorial sum of the transverse momenta of all PF candidates [24].
Events are selected if they have at least two identified photons with transverse energies above 40 and 25 GeV for the leading and subleading photons, respectively. Events are also required to have at least two jets with transverse energy above 30 GeV andjηj < 2.4 and satisfying the loose (CSV-loose)b-tag requirements, at least one of which also must pass the medium (CSV-medium) requirement. The CSV-loose and CSV-medium working points have signal efficiencies of 80%–85% and 50%–75%, respectively, and mistag rates from light-flavor jets of 8%–13% and 1%–2%, respectively[27].
The events with diphoton mass between 120 and 131 GeV constitute the signal sample, while the events with mass between 103 and 118 GeV and between 133 and 163 GeV compose the lower sideband and upper sideband samples, respectively.
In the investigated SUSY signal, b-quark jets can originate from decays of the other Higgs bosons and from decays of top squark. This is exploited by separating events into three categories with different expected backgrounds as follows: (i) events with at least one additional CSV-loose

b-quark jet in addition to the two (i.e., events with three or moreb-quark jets), (ii) events for which the invariant mass of the twob-quark jets is within a Higgs mass window from 95 to 155 GeV, and (iii) all other events.
The distribution of signal events among the three categories depends on the top squark and Higgsino masses. For small top squark-Higgsino mass differences, most of the signal populates category (ii), while for large mass differences categories (i) and (iii) dominate.
The search is performed independently in the three categories and the results are combined, leading to as much as 35% improvement in expected SUSY cross section limits compared to the analysis without categorization.
The peaking background from the SM Higgs boson production with subsequent diphoton decay is found neg-ligible using MC simulation. The diphoton mass sidebands are used to derive an estimate of all other SM background processes from data.
The diphoton distribution is fitted using a power law from 103 to 163 GeV [28]. The region from 118 to 133 GeV, corresponding to the signal region plus the 2 GeV“buffers” on each side of the signal region, is excluded from the fitter’s consideration to prevent a potential signal from affecting the background estimate. The result of the fit is used to calculate the normalization of the background. The effects of various other fit functions have been explored, and the resulting changes in the estimated background yields are well within the uncertainty in the fit function integral from the power law fit. The fit and background estimates are done independently in all three event categories.
Binned background distributions of relevant kinematic variables are obtained for each event category separately from the lower and upper sidebands and are weighted according to the fit function integrals. This provides two independent estimates of the distribution of the SM back-ground in the corresponding variable. No significant correlations are observed between the diphoton mass and other kinematic variables. However, to account for possible correlations, the background yield is conservatively assumed to be bounded by the independent background estimates from the upper and lower sidebands. The back-ground prediction using this bound as a systematic uncer-tainty is calculated as follows. The main background estimate in each bin of a kinematic variable is formed by taking an average of the two background estimates from the sidebands. Half the difference between the two esti-mates is taken as a systematic uncertainty for that bin, so that the central value and its uncertainty spans the range between the two estimates coming from the lower and upper sidebands. For the main variable used in this analysis, Emiss
T , the background uncertainty is dominated by the
statistical uncertainty in the sideband samples. The small correlation between the bin errors, originating from the common normalization from the fit, is taken into account during the statistical analysis described below.
The observed distributions of MeV are shown in Fig.3
separately for the three event categories, together with the background estimates from the above procedure and the expected distributions from three characteristic signal points. TableIshows the expected signal yields, background

predictions, and observed event counts for the three event categories. The observations are in agreement with the background predictions.
Since the data agree with the expected background, we proceed to set limits on the SUSY model described above. The expected limits were calculated using a variety of kinematic variables and it was determined thatEmiss
T is the
single most sensitive variable. The observed Emiss
T distributions for the three event
categories, shown in Fig. 3, together with the signal and background expectations listed in TableI, are used as input to the limit setting procedure.
A frequentist LHC-style profiled likelihood test statistic is used[29–31]. For each model mass point, the modified frequentist CLSmethod is used to calculate upper limits on
the cross section for the model.
The dominant uncertainty in the analysis is the statistical uncertainty of the background prediction. The leading sources of systematic uncertainties are the b-quark jet identification efficiency and the jet energy scale. The magnitude of the uncertainties depends on the event category and Emiss
T . Forb-quark jet identification it varies
from 1% to 5% for categories with two b-quark jets and from 6% to 17% for the three or more b-quark jets. For the jet energy scale, the uncertainty is important only for Emiss
T values below 40 GeV and varies from 7% to 43%.
Other sources of systematic uncertainty in the expected signal yield include the uncertainties in integrated lumi-nosity (2.6%)[32], the diphoton trigger efficiency (0.1%), the photon reconstruction and identification efficiency (1%), and the photon resolution uncertainty (1%)[4]. All system-atic uncertainties are correlated among the event categories and are treated as nuisance parameters in the likelihood, profiled according to their estimated value.
Figure4shows the limits on the GMSB model in the top squark-Higgsino mass plane. Depending on the Higgsino mass, and conservatively using the−1 standard deviation value for the theoretical cross section [16], top squark masses below 360 to 410 GeV are excluded at a 95% confidence level, corresponding to the region to the left of the leftmost thin dashed black line in Fig.4.
To summarize, a search for a natural SUSY scenario with light Higgsinos and a top squark was performed, using Higgs tagging in the diphoton decay mode, in a final state containing at least two photons and two or moreb-quark jets.
No evidence for a signal is observed, and 95% confidence level limits are set in the top squark-Higgsino mass plane, excluding a significant portion of the natural parameter space up to top squark masses of 410 GeV.
