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

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 $γγ$ excess while satisfying constraints from all other channels, given the specific set of extra fermions predicted by trinification.
