Testing lepton flavour universality in semileptonic ${\Lambda }_b\to {\Lambda }_c^{\ast }$ decays

Philipp Böer, Marzia Bordone, Elena Graverini +3

Lepton Flavour Universality tests with semileptonic ${\Lambda }_b\to {\Lambda }_c^{\ast }$ decays are important to corroborate the present anomalies in the similar ratios $R_{D^{(\ast )}}$, and can provide com…
