Query: A scalar hint from the diboson excess?   In view of the recent diboson resonant excesses reported by both ATLAS and
CMS Collaborations, we suggest that a new weak singlet pseudo-scalar particle,
$\eta_W$, may decay into two weak bosons while being produced in gluon fusion
at the LHC. The couplings to the gauge bosons can arise from a
Wess-Zumino-Witten anomaly term and thus we study an effective model based on
the anomaly term as a well motivated phenomenological model. In models where
the pseudo-scalar arises as a composite state, the coefficients of the
anomalous couplings can be related to the fermion components of the underlying
dynamics. We provide an example to test the feasibility of the idea.
