Query: $R_K$ anomalies and simplified limits on $Z'$ models at the LHC   The LHCb collaboration has recently reported a 2.5 $\sigma$ discrepancy with
respect to the predicted value in a test of lepton universality in the ratio
$R_{K^*}= \hbox{BR}(B \to K^* \mu^+ \mu^-) / \hbox{BR}(B \to K^* e^+ e^-)$.
Coupled with an earlier observation of a similar anomaly in $R_{K}$, this has
generated significant excitement. A number of new physics scenarios have been
proposed to explain the anomaly. In this work we consider simplified limits on
$Z'$ models from ATLAS and CMS searches for new resonances in dilepton and
dijet modes, and we use the simplified limits variable $\zeta$ to correlate the
results of the resonance and B-decay experiments. By examining minimal $Z'$
models that can accomodate the observed LHCb results, we show that the
high-mass resonance search results are begining to be sensitive to these models
and that future results will be more informative.
