Rather than being a single new species, the dark matter of the Universe could be a part of a more complicated collection of new particles with its own nontrivial dynamics that interacts weakly with the standard model--part of a ``dark sector.'' I will discuss motivations for considering this possibility, recent developments, and the new avenues for discovery that have opened up.
The leading dark matter (DM) paradigm over the past few decades has been that of a Weakly Interacting Massive Particle with a mass of tens of GeV to a few TeV. But in light of recent experimental constraints, attention is increasingly turning to models with lower-mass DM, especially in the context of a "dark sector" featuring dark mediators and multiple DM particle species. Probing such...
The Belle II experiment has started operations at the SuperKEKB e+e- collider, located at the KEK laboratory in Tsukuba, Japan. Like its predecessors Belle and BaBar, Belle II will operate near the Y(4S) resonance. It has the goal of collecting a dataset 100x larger than that of BaBar. The experiment's trigger has been designed to allow searches for a wide variety of dark sector particles and...
Despite the currently collected LHC datasets not seeming to show signs of easily observable physics beyond the Standard Model, there remains a number of areas still to be explored. One of these areas is the search for long-lived particles, typical signatures of Dark Sector models. These searches most often rely heavily on non-standard reconstruction within the ATLAS experiment. Standard...
