 ====== RF6: Dark Sector Studies at High Intensities ======
+Dark sectors — new physics neutral under Standard Model forces — can interact with ordinary matter through a few types of “portal” interaction constrained by Standard Model symmetries.  This possibility has gained attention both as a paradigm for dark matter (stable dark sector particles are natural dark matter candidates, and can realize thermal freeze-out below the Lee-Weinberg bound) and as a broad framework for exploring new, weakly coupled physics. Dark sector particles are expected to have very weak couplings to ordinary matter, and motivate dedicated searches in high-intensity experiments.  Simple and notable examples of dark sectors include low-mass dark matter interacting through a new force, minimal models of a scalar or vector mediator, and particles with weak long-range interactions such as millicharges.
