Nonperturbative parameters of inclusive Λ b decays from Small Velocity Sum Rules

Journal of High Energy Physics
We investigate the nonperturbative parameters entering the heavy quark expansion for the inclusive decay rates of the Λ b baryon, focusing on the kinetic term μ ̂ π 2 $$ {\hat{\mu}}_{\pi}^2 $$ and the Darwin term ρ ̂ D 3 $$ {\hat{\rho}}_D^3 $$ .

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

Analyzing the semileptonic and nonleptonic B c → J/ψ, η c decays

Journal of High Energy Physics
This study focuses on the decay of the B c meson to S-wave charmonia. Starting with lattice inputs on B c → J/ψ form factors, we have obtained the B c → η c form factors using heavy quark spin symmetry (HQSS) relations between the associated form factors

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 ...

Correlated study on some B c → P and B c → S wave channels in light of new inputs

Journal of High Energy Physics
This study investigates the decay modes of the B c meson, focusing on semileptonic and nonleptonic decay into S and P wave charmonia. The primary objective is to extract the shape parameter of the B c meson distribution amplitude through a data-driven ...
