Trinification can explain the di-photon and di-boson LHC anomalies

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 $W_R^{\pm }$ with a gauge coupling $g_R\approx 0.44$ that does not decay into leptons. Furthermore, trinification predicts extra scalars. One of them can reproduce the $\gamma \gamma$ excess while satisfying constraints from all other channels, given the specific set of extra fermions predicted by trinification.
