Detection of low-energy nuclear recoil events plays a central role in searches for particle
dark matter interactions with atomic matter and studies of coherent neutrino scatters. Precise …

Thermal dark matter models with particle χ masses below the electroweak scale can provide
an explanation for the observed relic dark matter density. This would imply the existence of a …

We point out that production of new bosons by charged meson decays can greatly enhance
the sensitivity of beam-focused accelerator-based experiments to new physics signals. This …

Sub-GeV dark matter (DM) particles produced via thermal freeze-out evade many of the
strong constraints on heavier DM candidates but at the same time face a multitude of new …

Beam dumps and fixed-target experiments have been very sensitive probes of such particles
and other physics beyond the Standard Model by considering the production of new states …

Electron beam fixed target experiments such as NA64 and LDMX use missing energy-
momentum to detect the production of dark matter and other long-lived states. The most …

We consider the potential for a 10 kg undoped cryogenic CsI detector operating at the
Spallation Neutron Source to measure coherent elastic neutrino-nucleus scattering and its …

A bstract Compared to other neutrino sources, the huge anti-neutrino fluxes at nuclear
reactor based experiments empower us to derive stronger bounds on non-standard …

We consider the possible production of a new MeV-scale fermion at the COHERENT
experiment. The new fermion, belonging to a dark sector, can be produced through the up …

Neutrinos with energy of order 10 MeV, such as from pion decay-at-rest sources, are an
invaluable tool for studying low-energy neutrino interactions with nuclei—previously …
