Phenomenology of $b\to c\tau \bar{\nu }$ decays in a scalar leptoquark model

Han Yan, Ya-Dong Yang, Xing-Bo Yuan

During the past few years, hints of Lepton Flavour Universality (LFU) violation have been observed in $b\to c\tau \bar{\nu }$ and $b\to s{\ell }^{+}{\ell }^{-}$ transitions. Recently, the $D^{\ast }$…
