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

open access: yesJournal 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

Semi-leptonic decays of a particle to three bodies

open access: yesVisión 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

Giovanni ONORATO 1. Rare B meson decays involving leptons: theoretical framework

open access: yes, 2009
In the Standard Model (SM), the purely leptonic decay B + → l + νl proceeds via quark annihilation into a W + boson.The branching fraction is: B(B + → l + νl) = G2 F mBm 2

Form factors for semi-leptonic B decays

open access: yes, 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.

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

open access: yesJournal 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 ...

Studying semi-leptonic b→(s,d)νν¯ decays in the MSSM without R-parity

open access: yes, 2009
We present a complete study of R-parity violating supersymmetric effects in thirteen exclusive and inclusive semi-leptonic b→(s,d)νν¯ decays; Bu+→K(∗)+νν¯, Bd0→K(∗)0νν¯, Bs0→ϕνν¯, Bd0→π0(ρ0)νν¯, Bu+→π+(ρ+)νν¯, Bs0→K(∗)0νν¯ and B→Xs,dνν¯ decay modes.
