The Mono-Tau Menace: From $B$ Decays to High-$p_T$ Tails

Admir Greljo, Jorge Martin Camalich, José David Ruiz-Álvarez

We investigate the crossing-symmetry relation between $b\to c{\tau }^{-}\bar{\nu }$ decay and $b\bar{c}\to {\tau }^{-}\bar{\nu }$ scattering to derive direct correlations of New Physics in semi-tauonic $B$-m…
