Description
Higgsino dark matter is one of the well-motivated candidates for weakly interacting massive particle WIMP dark matter. Collider searches provide an important and complementary probe of this scenario. Since Higgsinos form electroweak multiplets, the lightest neutral Higgsino dark matter candidate is accompanied by nearly degenerate charged and neutral Higgsino states. The collider phenomenology therefore depends sensitively on the mass spectrum, decay modes, and lifetimes of these states. In this talk, I will discuss precision calculations of quantum corrections to the Higgsino mass spectrum and decay properties. These corrections are essential for obtaining accurate predictions, especially in the compressed spectrum characteristic of Higgsino dark matter. I will then present the implications of these results for collider searches.
