Project description

The position is associated with rare event searches with XENONnT and preparation for the next generation rare event observatory XLZD. XENONnT is a dual-phase liquid xenon TPC at LNGS with a 5.9-tonne active mass, optimized for WIMP detection with sensitivity to spin-independent cross sections down to ~10⁻⁴⁸ cm². Its low backgrounds and improved calibration enable searches for low-energy electronic recoils from axions, dark photons, and other BSM candidates. The detector also probes CEνNS and sets limits on the neutrino magnetic moment and axion-electron couplings. XENONnT is part of the XLZD consortium, which aims to merge the expertise of the XENON, LUX-ZEPLIN, and DARWIN collaborations to realize a next-generation dark matter observatory.

Main responsibilities

The postdoctoral candidate is expected to focus on statistical data analysis including machine learning, Monte Carlo simulations, operations and calibration of the XENONnT detector as well as potentially, testing, characterization and development of photosensors.

Qualification requirements
