Title: The ATLAS diboson resonance in non-supersymmetric SO(10)

SO(10) grand uni cation accommodates intermediate gauge symmetries with which gauge coupling uni cation can be realized without supersymmetry. In this paper, we discuss the possibility that a new massive gauge boson associated with an intermediate gauge symmetry explains the excess observed in the diboson resonance search recently reported by the ATLAS experiment. The model we find has two intermediate symmetries, SU(4)C Ⓧ SU(2)L Ⓧ SU(2)R and SU(3)C Ⓧ SU(2)L Ⓧ SU(2)R Ⓧ U(1)B-L, where the latter gauge group is broken at the TeV scale. This model achieves gauge coupling uni cation with a uni cation scale su fficiently high to avoid proton decay. In addition, this model provides a good dark matter candidates, whose stability is guaranteed by a Z2 symmetry present after the spontaneous breaking of the intermediate gauge symmetries. In addition, we discuss prospects for testing these models in the forthcoming LHC experiments and dark matter detection experiments.
