Signal partitioning in superfluid 4He: A Monte Carlo approach — •Francesco Toschi for the DELight collaboration — Karlsruhe Institute of Technology, Institute for Astroparticle Physics — Heidelberg University, Kirchhoff-Institute for Physics
Superfluid 4He presents a compelling target for direct detection of light dark matter (LDM), offering both a low nuclear mass and a low energy detection threshold through quasiparticle generation. This talk will discuss the physical processes involved in the deposition of energy in superfluid 4He, focusing on the response to nuclear and electronic recoils, which are crucial for the detection of LDM. A Monte Carlo simulation framework has been developed to model the distribution of deposited energy across distinct signal channels for various recoil types. This work is essential for optimizing the design and performance of next-generation detectors such as the DELight experiment.
