Description
Sub-GeV, or light, dark matter (DM) has emerged as a compelling candidate for the observed DM in the universe. Unlike the canonical WIMP, light DM can account for the thermal relic abundance while evading nuclear recoil direct detection constraints, due to its limited momentum transfer. This motivates alternative search strategies, such as electron recoil direct detection and accelerator based experiments.
Upcoming experiments such as the Light Dark Matter eXperiment (LDMX), are projected to probe a broad range of DM scenarios, significantly extending the sensitivity frontier for light DM theories.
In this talk, we highlight new types of dark sector theories and processes that can be probed at LDMX and complementary experiments, focusing on two examples: a vector DM candidate arising from a dark SU(2) gauge symmetry, and a dark photon model featuring higher-order electromagnetic moments.
