| Description | Speaker: Xing Wang Title: Searching for Electroweak Dark Matter Host: Da Liu Room: 432 Abstract: Among the multitude of possibilities for particle DM, WIMPs remain a highly motivated candidate due to the predictable nature of the thermal relic abundance, and the correlated predictions for their experimental and observational probes. WIMP dark matter particles that belong to a multiplet of the standard model weak interactions are one of the best representatives, but are often challenging to probe in direct detection experiments due to loop-suppressed scattering cross-sections. Searches at hadron colliders are thus crucial for testing such a scenario. I will discuss the search channels at hadron colliders and present the projected reach at 14-TeV HL-LHC, 27-TeV HE-LHC, and 100-TeV hadron collider. While for the pure SU(2)L multiplets discussed above the tree-level SI scattering rates are absent due to symmetry reasons, there are other scenarios in which very small tree-level rates are obtained due to cancellations of different contributions to the relevant effective couplings, dubbed as blind spot. I will discuss the impact of one-loop electroweak corrections to the spin-independent dark matter (DM) scattering cross-section, in models with such blind spot for direct detection. |
