Taming new physics in b → cūd(s) with τ(B +)/τ(B d ) and a sl d $$ {a}_{sl}^d $$
Abstract Inspired by the recently observed tensions between the experimental data and the theoretical predictions, based on QCD factorisation, for several colour-allowed non-leptonic B-meson decays, we study the potential size of new physics (NP) effects in the decay channels b → cūd(s). Starting fr...
