The central detector is a low-background, two-phase time projection chamber 5.9 t sensitive...
We report on a blinded search for dark matter with single- and few-electron signals in the first science run of XENONnT relying novel detector response framework that is physics model dependent. derive 90% confidence upper limits matter-electron interactions. Heavy light mediator cases are considered standard halo up-scattered Sun. set stringent new scattering via heavy mass within <a:math xmlns:a="http://www.w3.org/1998/Math/MathML"...
A bstract Dark showers from strongly interacting dark sectors that confine at the GeV scale can give rise to novel signatures e + − colliders. In this work, we study sensitivity of B factory experiments produced through an effective interaction arising a heavy off-shell mediator. We show prospective search for displaced vertices GeV-scale long-lived particles Belle II improve substantially compared existing BaBar. compare searches signals promptly resonances BaBar and KLOE calculate...
Xenon is the target material of choice in several rare event searches. The use infrared (IR) scintillation light, addition to commonly used vacuum ultraviolet (VUV) could increase sensitivity these experiments. Understanding IR response xenon essential assessing potential for improvement. This study focuses on characterizing time and light yield (LY) gaseous alpha particles at atmospheric pressure room temperature. We have previously observed that can be described by two components: one with...
