  Extant anomalies in several semileptonic $B$-meson decays argue for physics
beyond the Standard Model. Measurements of both neutral-current decays (such as
$R_K$, $R_{K^*}$ and $B_s\rightarrow \phi\mu\mu$) as well as charged-current
ones- $R(D)$ and $R(D^*)$ -provide strong hints for the violation of lepton
flavor universality. Recent studies have shown that a class of effective field
theory (EFT) models may explain such anomalies in terms of only a few
parameters which can be determined phenomenologically. In this literature, we
examine such resolutions in the context of the requisite $(\bar{s}$
$b$)($\bar\tau\ \tau)$ operator, and look for its signals at the 13 TeV LHC,
with a final state of one $b$-jet, and an oppositely charged $\mu$-$\tau$ pair,
with the muon coming from the decay of one of the $\tau$ leptons. We obtain
discovery and exclusion limits on the model parameters as a function of
luminosity at the 13 TeV LHC.
