Direct detection prospects of dark vectors with xenon-based dark matter experiments

TL;DR

This paper reviews existing constraints and projects future sensitivity of xenon-based dark matter experiments, like XENON1T, to detect light dark photon vectors in the 0.01-100 keV mass range.

Contribution

It provides the first projected sensitivity estimates for XENON1T to detect dark photon vectors, expanding the search for light dark matter candidates.

Findings

Existing constraints on dark photon vectors in the 0.01-100 keV range.

Projected sensitivity of XENON1T to detect dark photons.

Potential to probe very light, weakly coupled dark matter particles.

Abstract

Dark matter experiments primarily search for the scattering of WIMPs on target nuclei of well shielded underground detectors. The results from liquid scintillator experiments furthermore provide precise probes of very light and very weakly coupled particles that may be absorbed by electrons. In these proceedings we summarize previously obtained constraints on long-lived dark matter vector particles $V$ (dark photons) in the $0.01-100$ keV mass range. In addition, we provide a first projected sensitivity reach for the upcoming XENON1T dark matter search to detect dark photons.
