Higgs Properties at the LHC

• Fabio Cerutti (LBNL)

After the discovery of a new neutral boson at LHC, the ATLAS and CMS collaboration have almost completed the analysis of the LHC Run 1 data. The first part of the talk will focus on what we have learnt on the Higgs boson from the current ATLAS and CMS Run 1 results. The properties measured by the two collaborations in terms of mass, Spin/CP and couplings to SM particles will be reviewed. The second part of the talk will focus on what will be the ultimate precision achievable on Higgs boson properties with the High Luminosity LHC run, which targets an integrated luminosity of 3000 fb-1 at 14 TeV. The projections from ATLAS and CMS collaborations in terms of CP determination and couplings, recently derived for the European Strategy and ECFA meetings, will be discussed.

Higgs Factories (circular and linear e+e-, pp, muon colliders, gamma-gamma-colliders, etc...)

• Alain Blondel (Geneve Univ.)

The discovery of the Higgs boson seems to close the Standard Model, but many questions remain unanswered for which one can envisage higher precision (to test the existence of very weakly coupled particles) or a higher reach in Energy. Various possibilities will be reviewed, and the CERN FCCs study of future circular colliders (VLHC and TLEP) will be shown to offer the best of both worlds.

Probing the Higgs mechanism with flavour physics: status and perspectives

• Frederic Teubert (CERN)

The flavour structure in the Standard Model (SM), and in many of its extensions, is completely determined by the mechanism that breaks the electroweak symmetry, i.e. the Higgs mechanism. The precision measurements in flavour changing neutral currents (FCNC) performed in the past at e+e- B-factories, today at LHCb and in a near future at the upgraded LHCb and Belle-II provide evidence for the Higgs mechanism as the correct solution. Moreover, in specific helicity suppressed FCNC decays, like Bs-->mu+mu-, the agreement with the SM put strong constrains on new scalar particles beyond the SM Higgs boson.
