Abstract
While the existence of dark matter has been largely accepted in the scientific community, its fundamental nature remains a mystery. Numerous experiments and collaborations aim to measure dark matter interactions arising from different theories, yet dark matter continues to elude us. Despite this, weakly interacting massive particles (WIMPs) stand out as one of the most compelling candidates that may explain the dark matter mystery. The DarkSide program aims to directly detect WIMPs with dual-phase argon time projection chamber (LAr TPC) technology. Currently in the construction phase at LNGS, Italy, the next-generation detector DarkSide-20k will be a 20-tonne fiducial volume argon TPC and is expected to set the best WIMP limits for masses above 1 TeV/c^2. This work focuses on three main aspects of the DarkSide program: calibration strategies and event position reconstruction methods for the DarkSide-20k detector, and a heavy dark matter (HDM) search with DarkSide-50, in which the case of composite HDM with varying dark nucleon masses is considered for the first time in the dual-phase argon TPCs.
