摘要We consider a simple solution to explain the recent diboson excess observed by ATLAS and CMS Collaborations in models with custodial symmetry SU(2)(L) x SU(2)(R) -> SU(2)(C). The SU(2)(L) triplet vector boson rho with mass range of 1.8 similar to 2 TeV would be produced through the Drell Yan process with sizable diboson decay branching to account for the excess. The other SU(2)(L) x SU(2)(R) bidoublet axial vector boson a would cancel all deviations of electroweak obervables induced by rho even if the SM fermions mix with some heavy vector-like (composite) fermions which couple to rho ("nonuniversally partially composite"), therefore allows arbitrary couplings between each SM fermion and rho. We present our model in the "General Composite Higgs" framework with SO(5) x U(1)(X) > SO(4) x U(1)(X) breaking at scale f and demand the first Wein-berg sum rule and positive gauge boson form factors as the theoretical constraints. We find that our model can fit the diboson excess very well if the left-handed SM light quarks, charged leptons and tops have zero, zero/moderately small and moderate/large composite components for reasonable values of g(rho) and f. The correlation between tree level S parameter and the h -> Z gamma suggest a large a contribution to h -> Z gamma and it is indeed a Omicron(1) effect in our parameter space which provides a strong hint for our scenario if this diboson excess is confirmed by the 13 similar to 14 TeV LHC Run II.
