High-energy physics

What Do We Learn From Higgs Couplings?
Abstract:
With the discovery of the Higgs boson, the important task becomes understanding the Higgs properties and in particular the couplings to fermions and gauge bosons. The measurement of these couplings can be used to probe possible new physics at high energy scales. I will discuss the uncertainties on the theoretical predictions of Higgs couplings and the interpretation of these measurements in terms of models with extended Higgs sectors or with other new heavy particles. The focus will be on the question: "How well do we need to measure Higgs couplings?

BSM Models Face Higgs Data
Abstract:
In this talk I will discuss how to probe Beyond Standard Model theories with Higgs coupling data. First, I will discuss how much Higgs couplings (including the Higgs self coupling) can deviate from their Standard Model values, in different BSM theories, if no other states are accessible at the LHC. We will argue that this is the Higgs coupling measurement precision that can serve as a target for experimentalists.
Multicomponent Dark Matter: Correlating Scattering Rates with Dark Sector Instability
Abstract:
Recent developments have suggested that the dark sector may be much more complex than previously imagined. As a result, models such as Dynamical Dark Matter --- in which there are multiple semi-stable dark matter components which contribute non-trivially to Omega --- merit further study. One interesting potential signal which arises in such contexts stems from the possibility of the inelastic scattering of heavier states into lighter states at direct-detection experiments.
The Search for the Higgs Boson Produced in Association with a Top Quark Pair
Abstract:
With the recent observation at ATLAS and CMS of a new particle, consistent with the Standard Model Higgs, with a mass near 125.7 GeV, the focus of the Higgs search has turned to testing whether the properties of this new particle are consistent with Standard Model expectations.
