Description
Inelastic Boosted Dark Matter (IBDM) models provide a multi-component dark sector scenario in which a relativistic dark matter state can inelastically scatter off matter producing distinctive electron-recoil like signatures. Unlike canonical WIMP interactions, IBDM events are expected to deposit significantly higher energies and may exhibit two collimated tracks with vertex displacement, depending on the underlying model parameters. Direct detection experiments are optimized for low energy recoils, but are also sensitive to this unconventional signature. DEAP-3600 is an example of such detector, which uses a 3.3 tonne liquid Ar target and has very low background, a highly efficient muon veto and, being installed at SNOLAB, has an extremely low muon flux. These features make it suitable for IBDM searches.
Signal modeling and event selection strategies are being developed to identify characteristic IBDM signatures in DEAP-3600 and suppress backgrounds. Based on these studies, in this talk I plan to address the projected sensitivity of DEAP-3600 to IBDM events over a representative region of model parameter space and compare it with the state of the art.
