Query: New vector bosons and the diphoton excess   We consider the possibility that the recently observed diphoton excess at
$\sim 750$ GeV can be explained by the decay of a scalar particle ($\varphi$)
to photons. If the scalar is the remnant of a symmetry-breaking sector of some
new gauge symmetry, its coupling to photons can be generated by loops of the
charged massive vectors of the broken symmetry. If these new $W^\prime$ vector
bosons carry color, they can also generate an effective coupling to gluons. In
this case the diphoton excess could be entirely explained in a simplified model
containing just $\varphi$ and $W^\prime$. On the other hand if $W^{\prime}$
does not carry color, we show that, provided additional colored particles exist
to generate the required $\varphi$ to gluon coupling, the diphoton excess could
be explained by the same $W^{\prime}$ commonly invoked to explain the diboson
excess at $\sim 2$ TeV. We also explore possible connections between the
diphoton and diboson excesses with the anomalous $t\bar{t}$ forward-backward
asymmetry.
