The nature of dark matter and properties of neutrinos are among the most pressing issues in
contemporary particle physics. The dual-phase xenon time-projection chamber is the …

The elastic scattering of an atomic nucleus plays a central role in dark matter direct detection
experiments. In those experiments, it is usually assumed that the atomic electrons around …

A bstract Motivated by the recent XENON1T results, we explore various new physics models
that can be discovered through searches for electron recoils in\(\mathcal {O}\)(keV) …

In the leading paradigm of modern cosmology, about 80% of our Universe's matter content is
in the form of hypothetical, as yet undetected particles. These do not emit or absorb radiation …

A key strategy for sub-GeV dark matter direct detection is searches for small ionization
signals that arise from dark matter-electron scattering or from the “Migdal” effect in dark …

If dark matter (DM) particles are lighter than a few MeV/c 2 and can scatter off electrons, their
interaction within the solar interior results in a considerable hardening of the spectrum of …

We show that the electron recoil excess around 2 keV claimed by the Xenon Collaboration
can be fitted by dark matter (DM) or DM-like particles having a fast component with velocity …

LUX-ZEPLIN is a dark matter detector expected to obtain world-leading sensitivity to weakly-
interacting massive particles interacting via nuclear recoils with a∼ 7-tonne xenon target …

We outline laser interferometer measurements to search for variation of the electromagnetic
fine-structure constant α and particle masses (including a nonzero photon mass). We …

Dark matter direct detection experiments have limited sensitivity to light dark matter (below a
few GeV), due to the challenges of lowering energy thresholds for the detection of nuclear …
