Heavy quark symmetry behind b → c semileptonic sum rule
Abstract Lepton flavor universality violations in semileptonic b → c transitions have garnered attention over a decade. For $${R}_{{H}_{c}}={\text{BR}}\left({H}_{b}\to {H}_{c}\tau {\overline{\nu }}_{\tau }\right)/{\text{BR}}\left({H}_{b}\to {H}_{c}{\ell}{\overline{\nu }}_{{\ell}}\right)$$ with ℓ bei...
