Query: Stringy origin of diboson and dijet excesses at the LHC   Very recently, the ATLAS and CMS collaborations reported diboson and dijet
excesses above standard model expectations in the invariant mass region of 1.8
-2.0 TeV. Interpreting the diboson excess of events in a model independent
fashion suggests that the vector boson pair production searches are best
described by WZ or ZZ topologies, because states decaying into W^+W^- pairs are
strongly constrained by semileptonic searches. Under the assumption of a low
string scale, we show that both the diboson and dijet excesses can be steered
by an anomalous U(1) field with very small coupling to leptons. The Drell-Yan
bounds are then readily avoided because of the leptophobic nature of the
massive Z' gauge boson. The non-negligible decay into ZZ required to
accommodate the data is a characteristic footprint of intersecting D-brane
models, wherein the Landau-Yang theorem can be evaded by anomaly-induced
operators involving a longitudinal Z. The model presented herein can be viewed
purely field-theoretically, although it is particularly well motivated from
string theory. Should the excesses become statistically significant at the
LHC13, the associated Z\gamma{} topology would become a signature consistent
only with a stringy origin.
