Estimates of the isospin-violating $Λ_{b} \to Σ^{0} ϕ, Σ^{0} J / ψ$ decays and the $Σ - Λ$ mixing

Zhou Rui, Jia-Ming Li, Chao-Qi Zhang

We analyse the two purely isospin-violating decays $Λ_{b} \to Σ^{0} ϕ$ and $Λ_{b} \to Σ^{0} J / ψ$ , proceed merely via the exchange topologies, in the framework of perturbative…

Nonleptonic two-body decays of $Λ_{b} \to Λ_{c} π, Λ_{c} K$ in the perturbative QCD approach

Chao-Qi Zhang, Jia-Ming Li, Meng-Kun Jia +1

We study the color-allowed $Λ_{b} \to Λ_{c} π, Λ_{c} K$ decays in the perturbative QCD approach (PQCD) to lowest order in strong coupling constant $α_{s}$ . Both the factorizable and…

$C P$ -violating observables in four-body $B \to ϕ (\to K K ˉ) K^{*} (\to K π)$ decays

Chao-Qi Zhang, Jia-Ming Li, Meng-Kun Jia +2

We analyse the four-body $B \to ϕ (\to K K ˉ) K^{*} (\to K π)$ decays in the perturbative QCD approach,where the invariant mass of $K K ˉ$ ( $K π$ ) system is limi…
