Description

The nature of non‐baryonic dark matter (DM) is one of the most intriguing questions for particle physics at the start of the 21st century. The Chicagoland Observatory for Underground Particle Physics (COUPP) employs a CF3I bubble chamber to search for WIMP‐nucleus elastic scattering events. In this communication we show the plans, status and results of COUPP in the different bubble chamber generations (4 kg, 60 kg and 500 kg). We will put, as well, special attention to the acoustic technique employed to be able to discriminate bubbles from alphas allowing a large background reduction and thus increasing the sensitivity
