Form factors for semi-leptonic B decays

, 2016
Semi-leptonic $B$ decays provide promising channels to test the Standard Model, search for signs of new physics, or determine fundamental parameters like CKM matrix elements.

$Ω_b$ semi-leptonic weak decays

, 2011
$Ω_b \rightarrow Ω_c^{(*)}$ semi-leptonic decays are studied in details. Relevant helicity amplitudes are written down. Both unpolarized and polarized $Ω_b$ cases are considered. Decay angular distributions, asymmetry parameters and semileptonic decay rates are calculated, with numerical results using leading order results of the large $N_c$ and heavy ...

SCET sum rules for Λ b → Λℓ + ℓ − , Λγ decays

Journal of High Energy Physics
We construct light-cone sum rules for various types of effective form factors in the Λ b → Λℓ + ℓ − and Λ b → Λγ decays by analyzing vacuum-to-Λ b (or γ *-to-Λ b ) correlation functions with the light Λ-baryon interpolating current.

Study of form factors and observables in B c − → D s ∗ − ℓ + ℓ − $$ {B}_c^{-}\to {D}_s^{\ast -}{\ell}^{+}{\ell}^{-} $$ and B c − → D s ∗ − ν ν ¯ $$ {B}_c^{-}\to {D}_s^{\ast -}\nu \overline{\nu} $$ decays

Journal of High Energy Physics
We investigate the decays B c − → D s ∗ − ℓ + ℓ − $$ {B}_c^{-}\to {D}_s^{\left(\ast \right)-}{\ell}^{+}{\ell}^{-} $$ and B c − → D s ∗ − ν ν ¯ $$ {B}_c^{-}\to {D}_s^{\left(\ast \right)-}\nu \overline{\nu} $$ within the Standard Model (SM), employing ...

Review of D Semi-leptonic Decays

, 2012
Semi-leptonic D decays continue to play an important role in the field of flavor physics. During this presentation, recent measurements from pseudo-scalar to pseudo-scalar modes, pseudo-scalar to vector modes, and rare modes will be discussed. These results are important for many purposes, such as validating the machinery of lattice QCD, extracting CKM

Semi-leptonic decays of a particle to three bodies

Visión electrónica, 2018
Is presented the dynamics and kinematics of the semi-leptonic decays with interaction  V-A calculating the decay width and the fraction of decay for each process using spectator model. The results are compared with the experimental data of the table particle data group, which show that the model prediction for this type of decay can be considered as a
