"Non-universal gauge interaction model exclusion limit" of "Search for new physics in the $\tau$ lepton plus missing transverse momentum final state in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

Bayesian lower exclusion limits on the NUGIM G(221) mixing angle $\cot(\theta_{E})$
are shown as a function of the W$\prime$ boson mass. The theoretically excluded region is shaded in grey.
The 68 and 95% quantiles of the limits are represented by the green and yellow bands, respectively.
