Direct detection constraints on EFT operators for inelastic dark matter

Year: 2026

Type: preprint

Abstract: We convert existing exclusion limits on the elastic spin-independent (SI) dark matter--proton cross sections into upper bounds on the event rate, subsequently applying them to constrain other effective operators for inelastic scattering of light dark matter in the GeV mass region. We focus on three representative scenarios including the isoscalar, proton-philic, and the proton-philic spin-dependent inelastic dark matter model, which are well-motivated in phenomenological studies of dark matter detection.
