The relic density of TeV-scale wino-like neutralino dark matter in the MSSM is subject to potentially large corrections as a result of the Sommerfeld effect. A recently developed framework enables us to calculate the Sommerfeld-enhanced relic density in general MSSM scenarios, properly treating mixed states and multiple co-annihilating channels as well as including off-diagonal contributions....

Current status of spin-independent (SI) direct detection experiments may suggest that the WIMP dark matter (e.g. nuetralinos in supersymmetric models) would interact very weakly with nucleons. The so-called blind spots in parameter space correspond to the limit of vanishing SI interaction. In my talk I will discuss several classes of blind spots of NMSSM and their influence on the relic...

The general strategy for dark matter (DM) searches at colliders currently relies on simplified models, which typically have a limited number of free parameters. In the case of t-channel colored mediators, these simplified models often have assumptions on the chirality of the DM-SM interactions with quarks, though generically a UV-complete model with such colored mediators would lead to...

In this talk, we will discuss the prospects of a simple extension of the minimal supergravity (mSUGRA) model to which we add three generations of right handed neutrinos (sneutrinos). The neutrino masses are assumed to be of a purely Dirac nature. In this framework, the right-handed sneutrino becomes the cold dark matter candidate (CDM) of the universe. We consider the production of the...

I will present a general classification of simplified models of dark matter coannihilation and discuss the main phenomenological features of these models. The fully general treatment of coannihilation allows for new exotic mediators to the dark sector that should be tackled with non-standard collider search strategies. In this talk, general classes of LHC signatures describing the full set of...
