Query: Vector Leptoquarks and the 750 GeV Diphoton Resonance at the LHC   The ATLAS and CMS collaborations recently presented evidence of a resonance
decaying to pairs of photons around 750 GeV. In addition, the BaBar, Belle, and
LHCb collaborations have evidence of lepton non-universality in the
semileptonic decays of $B$ mesons. In this work, we make a first step towards a
unified explanation of these anomalies. Specifically, we extend the Standard
Model by including vector leptoquarks and a scalar singlet that couples
linearly to pairs of the leptoquarks. We find there is parameter space that
gives the correct cross section for a putative 750 GeV resonance decaying to
photons that is consistent with unitarity, measurements of the properties of
the 125 GeV Higgs boson, and direct searches for resonances in other channels.
In addition, we also show that constraints can be derived on any Beyond the
Standard Model explanation of the 750 GeV resonance where the only new
particles are scalars, which are strong enough to rule out certain types of
models entirely.
