S02.00001: New Dark Sector Experiments at Accelerators Invited Speaker: Nhan Tran The program to search for dark matter in the past couple of decades has mostly focused on WIMPs at the GeV - TeV scale. It has made impressive strides in sensitivity but has yet to unearth the particle nature of dark matter. Recently there have been many new initiatives to broaden the search for dark matter, many of them smaller scale experiments. One of the main thrusts of this recent dark matter initiative is to extend searches for dark matter below the GeV-scale using accelerator techniques. I will lay out the various accelerator approaches to look for dark matter in this regime including beam dump and fixed target missing momentum techniques. I will discuss their complementarity with each other and with non-accelerator-based experiments. [Preview Abstract] |

S02.00002: Synergies between Dark Matter and Neutrino Experiments Invited Speaker: Louis Strigari Direct dark matter detection experiments will soon be sensitive to neutrinos from astrophysical sources, in particular the Sun, the atmosphere, and supernovae. This provides an opportunity for these experiments to make important contributions to neutrino physics and astrophysics. I will discuss the prospects for studying neutrinos with future experiments, and will highlight the synergies with terrestrial experiments studying neutrinos in this same energy regime.

S02.00003: Direct Dark Matter Detection above the Proton Mass Invited Speaker: Cecilia Levy The direct search for dark matter is an exciting field of particle physics. Many different experiments using many different techniques are looking for this particle, which remains elusive to this day. In this talk, I will focus on the current and future experiments looking for WIMP dark matter with masses above ~1 GeV, particularly, liquid noble detectors based on xenon and argon that have provided the most competitive searches for WIMP dark matter, having probed orders of magnitude in cross section over the past decades. The upcoming, high discovery potential experiments, LZ and XENONnT, will be highlighted, as well as the plans for future G3 experiments, where sensitivity to WIMP-nucleon cross sections down to the neutrino floor will be reached.
