12 The minimal, weakly-‐coupled SM

with a single “elementary” scalar doublet breaking the gauge and ﬂavour symmetries

works far beyond most expectations against tests at growing precision and energy There was evidence before from

LEP, Tevatron, B-‐factories, etc After LHC Run 1:

stronger and more direct evidence

(13)

13 •  Mass where favoured by EW precision tests

•  Couplings to vectors and fermions as in SM

•  No signs of exotic states in γγ or gg loops

•  No signs of mixing with other states

•  No signs of invisible decay channels

•  No signs of additional Higgs bosons

…all with still large errors, but…

The minimal, weakly-­‐coupled SM

with a single “elementary” scalar doublet breaking the gauge and ﬂavour symmetries

works far beyond most expectations against tests at growing precision and energy There was evidence before from

LEP, Tevatron, B-­‐factories, etc After LHC Run 1:

stronger and more direct evidence

13

• Mass where favoured by EW precision tests

• Couplings to vectors and fermions as in SM

• No signs of exotic states in γγ or gg loops

• No signs of mixing with other states

• No signs of invisible decay channels

• No signs of additional Higgs bosons

…all with still large errors, but…
