Searches for invisible decays of the Higgs boson at the LHC
In this talk I will present an overview of searches for invisible decays of the Higgs boson undertaken at the ATLAS and CMS experiments. I will review recent results from direct searches for invisible decays as well as constraints from measurements of visible decay widths, and discuss available combinations and interpretations.
Search for Higgs to invisible using vector boson fusion
The search for invisible decays of the Higgs boson is most sensitive in the vector boson fusion channel. This talk will cover experimental aspects of the search for Higgs to invisible, with emphasis VBF. I will begin with an overview of techniques used in run 1, then discuss planned improvements for run 2. This will include an updated...
Dark Matter in Vector Boson Fusion
VBF is a promising probe for dark matter that interacts with the electroweak sector. In this talk, I will discuss several different manifestations of such models and the potential reach of VBF searches at high-energy colliders.
The direct invisible Higgs bounds are driven by two main searches at hadron colliders: WBF and ZH. For the WBF, we will present some recent progress made on the Monte Carlo modelling and show the prospects of this measurement at the 100 TeV Nimatron. For the ZH, we will show that loop-induced components for both the signal and background present phenomenologically relevant contributions to...
Identifying the Nature of Dark Matter via Higgs portal.
There are three types of the models depending on the DM spin: scalar, fermion and vector DM models. In this talk, we consider renormalizable, unitary and gauge invariant Higgs portal DM models. For the Higgs portal singlet fermion and vector DM cases, the force mediator involves two scalar propagators, the SM-like Higgs boson and the...
