Study of form factors and observables in B c − $$ {B}_c^{-} $$ → D ¯ ∗ 0 ℓ − ν ¯ ℓ $$ {\overline{D}}^{\left(\ast \right)0}{\ell}^{-}{\overline{\nu}}_{\ell } $$ and B c − $$ {B}_c^{-} $$ → D (∗)− ℓ + ℓ − decays

Abstract We investigate the decays B c − $$ {B}_c^{-} $$ → D ¯ ∗ 0 ℓ − ν ¯ ℓ $$ {\overline{D}}^{\left(\ast \right)0}{\ell}^{-}{\overline{\nu}}_{\ell } $$ and B c − $$ {B}_c^{-} $$ → D (∗)− ℓ + ℓ − within the Standard Model (SM), employing perturbative QCD (pQCD) form factors that are sensitive to th...
