BULLKID-DM: searching for light WIMPs with monolithic detector arrays

Abstract

BULLKID-DM is a novel experimental effort in the field of dark matter detection, aimed at searching for hypothetical WIMP-like particles with a mass around 1 GeV/c² and a nucleon cross-section below 10⁻⁴¹ cm². The detector will feature an 800 g target composed of 2,500 silicon dice, instrumented with phonon-mediated kinetic inductance detectors. Compared to other solid-state experiments in the field, BULLKID-DM seeks to achieve superior background rejection by constructing a fully active detector volume and employing fiducialization techniques. The experiment is planned to be installed in Italy at the Gran Sasso National Laboratory (LNGS). In this seminar we present results from a 60 g demonstrator array comprising 180 silicon dice, provide an update on the construction status of the full experiment, and discuss the projected dark matter sensitivity.
