Abstract:

Precision measurements of the 125 GeV Higgs resonance recently discovered at the LHC have determined that its properties are similar to the ones of the Standard Model (SM) Higgs boson. However, the current uncertainties in the determination of the Higgs boson couplings leave room for significant deviations from the SM expectations. In fact, if one assumes no correlation between the top-quark and gluon couplings to the Higgs, the current global fit to the Higgs data lead to central values of the Higgs couplings to the bottom-quark and the top- quark that are about 2 σ away from the SM predictions. In this talk we shall discuss theoretical models which could lead to a sizable enhancement (suppression) of the top-quark (bottom-quark) coupling to the Higgs  and present some testable implications of these models.

The speaker is the Head of the ANL High Energy Physics Theory Group and Professor at the EFI and the KICP, University of Chicago
