2403. Dark matter in a dark sector

Symposia Day - Dark Matter

Invited Speaker / Conférencier(ère) invité(e)

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.

Invited Speaker / Conférencier(ère) invité(e)

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...

2409. Dark sector, dark matter, and related searches at Belle II

Invited Speaker / Conférencier(ère) invité(e)

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...

2404. Dark Sector Searches on ATLAS

Symposia Day - Dark Matter

Invited Speaker / Conférencier(ère) invité(e)

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...
