03/08/2017HEP SeminarRouven EssigDirect Detection of sub-GeV Dark Matter [ -- Description ]

Description: Dark matter with MeV-to-GeV masses is a theoretically and phenomenologically appealing possibility. In this talk, I will describe how direct-detection experiments can probe this under-explored mass range. A demonstrated technique with significant potential for improvement is that dark matter scatters off electrons, causing ionization or excitation of atoms in a detector target material, which can lead to events containing one or more electrons or photons. I will describe how XENON10 data probes dark matter with masses as low as a few MeV, and present improved constraints from both XENON10 and XENON100 for masses above 50 MeV. After reviewing the prospects and challenges for xenon-based experiments to make further progress, I will discuss how experiments with different materials could significantly improve the sensitivity. This includes upcoming experiments using semiconductors as well as new dedicated experiments using scintillators and other materials. I will especially highlight SENSEI, a new ultra low-threshold Si-detector, which can improve on current sensitivities by many orders of magnitude over the next few years. I will also present a few simple sub-GeV dark matter models, which provide concrete experimental targets, and contrast direct-detection probes with searches at colliders and fixed-target experiments.
