We will report the latest development of NEST, a comprehensive simulation package for noble liquid experiments. It has achieved increasingly accurate predictions of energy spectrum and discrimination between electronic and nuclear recoils for a large range of drift fields in liquid xenon and is used by leading dark matter experiments such as LZ and XENONnT. Opportunities to use this software...
The LUX-ZEPLIN (LZ) detector is a 10-ton liquid xenon dual-phase time projection chamber operating at the SURF laboratory (South Dakota, USA). As reported in June 2022, after 60 live days of the search for Weakly Interacting Massive Particles (WIMPs), LZ demonstrates a world record sensitivity to spin-independent WIMP-nucleon interactions for WIMP masses above 9 GeV [1]. Given its large target...
The MicroBooNE detector is an 85-ton active mass Liquid Argon Time Projection Chamber (LArTPC) located on-axis along the Booster Neutrino Beam (BNB). It serves as a part of the Short-Baseline Neutrino (SBN) program at Fermilab, which was primarily designed to address the Miniboone low-energy excess. The primary signal in the LArTPC is ionisation, but the argon also emits large quantities of...
Pulse Shape Discrimination is a powerful tool to distinguish WIMP signals from electronic recoil background in liquid Argon detectors.
In order to accurately evaluate the expected rate of background events with uncertainty, a robust background model that can be tuned to the detector data and reliably extrapolated orders of magnitude beyond the available background statistics, is needed. We...
Pulse shape discrimination (PSD) is a powerful tool for separating gamma induced interactions from those induced by fast neutrons. It relies on the fact that various excited modes have different decay constants, and are excited differently by neutrons and gammas. This is especially true for liquid argon targets. We have designed and developed a custom integrated circuit that reads out...
Supernova neutrinos produced during a core-collapse of a massive star, carries 99% of the energy produced during the violent phenomenon. These neutrinos are weakly interacting massive particles, and can provide useful information for both particle physics (neutrino oscillations parameters ) and astrophysics (explosion mechanism) that can be used to explore physics beyond the standard model....
