Direct detection for heavy wimp dark matter

Speaker(s) / Presenter(s):
Qing Chen
In this talk, I'll introduce wimps as a large class of viable dark matter candidates and experiments aiming to search for them. I'll focus on heavy wimps (mass greater than electroweak scale) direct detection experiment rate calculations, particularly for higgsino-like and wino-like particles. There's a cancellation between leading order amplitudes and the overall cross sections are much suppressed, leaving them at least an order below current direct detection experimental limits. It is important to consider all the subleading effects to see whether they will change the leading order result and to predict reliable benchmark results for next generation experiments.
