A scalar-mediated inelastic dark matter model with 100 eV splitting, Z2 symmetry forbidding elastic scattering, and a dimension-5 dipole operator reconciles dwarf galaxy observations with cosmological bounds via resonant enhancement and provides a distinct direct detection signal.
The radial Hamiltonian for a partial wave l is: d2 dr2 + K 2 − l(l + 1) r2 − 2µV (r) ul(r) = 0 , (A1) where ul = ( ul,1, ul,2)T

Scalar-Mediated Inelastic Dark Matter as a Solution to Small-Scale Structure Anomalies
A scalar-mediated inelastic dark matter model with 100 eV splitting, Z2 symmetry forbidding elastic scattering, and a dimension-5 dipole operator reconciles dwarf galaxy observations with cosmological bounds via resonant enhancement and provides a distinct direct detection signal.
