Abstract: Dark matter which carries hypercharge is a generic possibility which leads to very large scattering cross sections at direct detection experiments. In fact, current and planned experiments are probing masses for such particles up to an amazing 10^8-10^10 GeV. If a detection were made, then the scattering rate would reveal the dark matter mass, and in turn an indirect measurement of the reheating temperature of the universe through its impact on the non-thermal dark matter relic abundance. Evidence that hypercharged dark matter were responsible for a signal could be obtained by comparing spectra at several experiments. To this end, I will discuss a new and improved approach for removing uncertainty due to the unknown halo velocity distribution.
