Abstract: BULLKID-DM is an experiment searching for hypothetical WIMP-like particles with mass around 1 GeV/c² or lower and with nucleon cross-section below 10⁻⁴¹ cm². The detector will feature an 800 g target composed of 2300 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 using 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 I will present results from a 60 g demonstrator array of 180 silicon dice, provide an update on the status of the full experiment, and discuss the projected dark matter sensitivity.
