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
Potential involvement in the testing, characterization, and development of photosensors

Qualification Requirements

To qualify for this postdoctoral position, applicants must:

Hold a Swedish doctoral degree in a relevant subject or an equivalent degree from another country
