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

Journal of High Energy Physics
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 ...

On soft contributions to the B − → γ * form factors

Journal of High Energy Physics
The photoleptonic decay B − → γ ℓ − ν ¯ $$ {B}^{-}\to \gamma {\ell}^{-}\overline{\nu} $$ is the simplest low-energy process that probes the substructure of the B meson, making it an excellent candidate to determine the parameters of B-meson light-cone ...

Searches for Rare Leptonic and Semileptonic Charm Decays at BaBar [PDF]

, 2007
Recent results from leptonic and semi-leptonic charm decays at the BABAR B-factory are presented. The measurement of f{sub D{sub s}} from the D{sub s}{sup +} {yields} {mu}{sup +}{nu} channel is presented.

Semi-leptonic decays at the Belle and Belle II experiments

, 2022
© 2022 Daniel Adam FerlewiczThis thesis explores semi-leptonic decays of the type $B \to V L$ along two avenues; their contribution to high-precision tests and metrology of the Standard Model, and their potential for probing physics beyond the Standard ...

Radiative B decay spectrum: DGE at NNLO.

, 2007
We compute the differential ¯B → Xsγ decay width in the Standard Model as a function of the photon energy using Dressed Gluon Exponentiation (DGE).

Disentangling new physics in K → πν ν ¯ $$ K\to \pi \nu \overline{\nu} $$ and B → K K ∗ ν ν ¯ $$ B\to K\left({K}^{\ast}\right)\nu \overline{\nu} $$ observables

Journal of High Energy Physics
We investigate the possibility of disentangling different new physics contributions to the rare meson decays and through kinematic distributions in the missing energy .
