GUT-induced collider signatures of the LUX-ZEPLIN event

Abstract
The recent observation of an event with large recoil energy at LUX-ZEPLIN (LZ) has found a possible explanation in terms of the inelastic scattering of a pseudo-Dirac particle, for example, the Higgsino of the MSSM. For pseudo-Dirac dark matter, the mass splitting δm is correlated with the mass of some heavier states. While in the MSSM rough dimensional considerations seem to indicate mass ranges of these heavy particles hopelessly out of reach even at future colliders, we point out that this is not the case in GUT-induced scenarios, with or without supersymmetry. Working in a non-supersymmetric model based on SU(6), we show that the experimentally favored δm implies the presence of a Z' gauge boson with a mass of several TeVs. We derive the predicted Z' signal in the dilepton channel and we confront it with the sensitivity of the HL-LHC and the FCC-hh to Z' resonances. We show that the Z' falls squarely in reach of the discovery potential of both experiments.
