Signals and backgrounds in dark matter searches
As the various experimental searches for particle dark matter increase in size and improve in sensitivity, new challenges will arise in attempts to extract a possible signal. For direct dark matter searches, an important background in the future will be the "neutrino floor"; this is defined as the scale at which detectors are large enough to detect neutrinos produced from the Sun, atmosphere, and supernovae. Detectors are now fast approaching the scale at which these neutrinos will appear, so it is imperative to make a concerted effort towards understanding their spectra so that they may be properly identified. In this talk I will discuss theoretical and experimental methods that can be used to identify neutrino backgrounds, with the ultimate goal of pushing down the sensitivity of dark matter searches to cross sections that lie below the neutrino floor.
