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 $$ {\hat{\rho}}_D^3 $$ .

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 ...

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

Quantum entanglement and Bell inequality violation in semi-leptonic top decays

Journal of High Energy Physics
Quantum entanglement is a fundamental property of quantum mechanics. Recently, studies have explored entanglement in the t t ¯ $$ t\overline{t} $$ system at the Large Hadron Collider (LHC) when both the top quark and anti-top quark decay leptonically ...

$\Omega_b$ semi-leptonic weak decays

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