"Higgs Discovery: Is there New Physics?"
Abstract: In the wake of the discovery of a Higgs-like resonance near
125 GeV at the LHC, determining its properties in detail has become
extremely important. The observed production and decay modes appear to
be broadly consistent with those expected from a Standard Model Higgs.
However, there are hints that some modes (decays to two photons in
particular) may show some discrepancy with Standard Model predictions.
While future data will shed light on this possibility, we explore the
effects that an extended scalar sector and vector-like fermions can have
on Higgs' properties. We study the sensitivity of LHC experiments and
those at lower energies to scenarios where the Higgs differs from that
of the Standard Model.
