Thursday Afternoon: Dark Matter
- Julian Heeck
To date, only two modes of production at hadron colliders of dark matter through new scalar or pseudoscalar mediators with Yukawa-like couplings to Standard Model particles have been considered in the existing literature: pairs of dark matter particles produced through top quark loops with an associated hadronic jet in the event (monojet), and production of dark matter with pairs of heavy...
In this talk we will discuss the present status of theoretical studies and experimental searches performed in order to measure the di-Higgs process in various standard model (SM) final states. Furthermore, we will review the prospects of observing such channels at the 14 TeV high luminosity (HL) run of the large hadron collider (LHC). We will then discuss the prospects of observing certain...
The Higgs sector is a well-motivated portal to dark matter (DM). I discuss scalar/pseudoscalar portal models for DM, as a powerful tool to exploit the complementarity between LHC searches and direct/indirect DM detection experiments, and their connection to Higgs physics. I then analyze the shortcomings of so-called "simplified DM models" in this context, highlighting the key physics these...
The dark photon, $A′$, the dark Higgs boson, $h′$, and the dark baryon, $B'$, are hypothetical constituents featured in a number of recently proposed Dark Sector Models. Search for these particles are performed in the so-called dark Higgs-strahlung and radiative processes, and in neutral $D-$meson decays channels. We will present results for the search of dark sector particles with prompt and...
A direct approach to the dark matter detection is to measure the nuclear recoils produced in the scattering of DM particles off the nuclei of target materials in detectors placed deep underground.
The XENON1T experiment is the third phase of the XENON program and is aiming at direct DM detection. It consists of a double phase time projection chamber filled with about 2 t of liquid xenon and...
