<p>Joint Theory Seminar Speaker: Asher Berlin (SLAC)<br />mail: berlin@slac.stanford.edu<br />Title: Thermal Relics Below an MeV<br />Host: Verhaaren<br />Room: 432<br />Abstract: I will discuss a class of models in which thermal dark matter is lighter than an MeV. If dark matter thermalizes with the Standard Model below the temperature of neutrino-photon decoupling, constraints from measurements of the effective number of neutrino species are alleviated. This framework motivates new experiments in the direct search for sub-MeV thermal dark matter and light force carriers.</p>
