WIMPless Dark Matter and Meson Decays with Missing Energy

Understand

WIMPless dark matter offers an attractive framework in which dark matter can be very light.

• We investigate the implications of such scenarios on invisible decays of bottomonium states for dark matter with a mass less than around $5 {\rm GeV}$.
• We relate these decays to measurements of nucleon-dark matter elastic scattering.
• We also investigate the effect that a coupling to $s$ quarks has on flavor changing $b\to s$ processes involving missing energy.
