W4-7 Candidates for Dark matter and Dark sector II (PPD) / Candidats pour matière et secteur sombres II (PPD)
- David Morrissey (University of Michigan)
Data collected at the LHC are analyzed by the ATLAS collaboration for evidence of dark matter. In this talk, a fast simulation of the ATLAS detector response using the Delphes software is assessed for dark matter models with a leptonically decaying $Z$ boson and a pair of dark matter particles ($\chi\bar{\chi}$) in the final state. Limits for the Two Higgs Doublet plus pseudoscalar (2HDMa)...
We identify potentially the world's most sensitive location to search for millicharged particles in the 10 MeV to 100 GeV mass range: the forward region at the LHC. We propose constructing a scintillator-based experiment, FORward MicrOcharge SeArch (FORMOSA) in this location, and estimate the corresponding sensitivity projection. FORMOSA, placed $\sim 500 \, \rm m$ downstream from ATLAS,...
The existence of dark matter is widely accepted, with a well motivated theoretical candidate being a class of particles known as WIMPs (weakly interacting massive particles), which appear in the spectra of many extensions to the standard model.
We explore a particular WIMP-like model in which fermionic dark matter weakly couples to the muon/tau sectors of the standard model through a new...
The kinematics of WIMP dark matter-nuclear scattering is drastically altered in the presence of inelastic dark matter, where the dominant dark matter component is up-scattered to a heavier state with certain mass splitting. With hundreds of keV mass splitting inelastic dark matter will evade the search in most direct detection experiments, where the momentum transfer is limited either by the...
