The impact of heavy-quark loops on LHC dark matter searches
Ulrich Haisch, Felix Kahlhoefer, James Unwin
If only tree-level processes are included in the analysis, LHC monojet searches give weak constraints on the dark matter-proton scattering cross section arising from the exchange o…
Loop-induced dark matter direct detection signals from gamma-ray lines
Mads T. Frandsen, Ulrich Haisch, Felix Kahlhoefer +2
Improved limits as well as tentative claims for dark matter annihilation into gamma-ray lines have been presented recently. We study the direct detection cross section induced from…
LHC and Tevatron bounds on the dark matter direct detection cross-section for vector mediators
Mads T. Frandsen, Felix Kahlhoefer, Anthony Preston +2
We study the interactions of a new spin-1 mediator that connects the Standard Model to dark matter. We constrain its decay channels using monojet and monophoton searches, as well a…
