DARWIN cosmogenic background paper published

Our work on the impact that the cosmogenic background can have on the search of rare physics channels with DARWIN has been published in EPJC

DARWIN is a proposed experiment that, in its baseline design, consists of a Time Projection Chamber (TPC)  immersed in 40 tons of liquid xenon. The low intrinsic background of the system makes DARWIN sensitive to rare physics channels, such as WIMP detection or neutrinoless double beta decay, among others. However, the cosmic muons are always crossing the detector and are a source of background that cannot be fully suppressed, but mitigated by placing the detector underground. The location of the experiment has not yet been decided and simulations are crucial to estimate the impact of the cosmogenic background in the search of these physics channels. In this paper, we present a study of this background for several underground laboratories that are suitable locations for the DARWIN experiment.
