The LZ inelastic splitting as a probe of anomaly mediation

The LZ 248 keV recoil candidate admits an interpretation in terms of pseudo-Dirac dark matter with a mixing-suppressed inelastic $Z$ interaction. In the MSSM, the Higgsino limit conflicts with the adopted solar-neutrino bound, while a gaugino realization requires an unprotected mass degeneracy. We realize such spectra...
