Abstract: LHC data show a diphoton excess at 750 GeV and a less significant diboson excess around 1.9 TeV. We propose trinification as a common source of both anomalies. The 1.9 TeV excess can be produced by the lightest extra vector: a WR± with a gauge coupling gR ≈ 0.44 that does not decay into leptons. Furthermore, trinification predicts extra scalars. One of them can reproduce the γγ excess while satisfying constraints from all other channels, given the specific set of extra fermions predicted by trinification.
Trinification can explain the di-photon and di-boson LHC anomalies
