Study of $K π$ final states from four-body deacy of $B ˉ_{s}$ meason under perturbation QCD

Jiao Wu, Na Wang, Gang Lü +1

In the perturbative QCD framework, we use the quasi-two-body method to study the CP violations and branching ratios in the $\bar B_{s} \rightarrow [ϕ(ρ^{0},ω)\rightarrow K^{+}K^{-}…

The $C P$ violations and branching ratios for $B_{c}^{+} \to D_{(s)}^{+} π^{+} π^{-} (K^{+} K^{-})$ from interference of the vector mesons in Perturbative QCD

Kun Shuai Ye, Gang Lü, Na-Wang +2

Within the framework of the perturbative QCD approach utilizing $K_{T}$ factorization, we have investigated the CP violations and branching ratios in the decay processes of $B_{c}^{+…

CP asymmetry from the effect of the isospin symmetry breaking during B-meson decay

Wan-Ying Yao, Gang Lü, Xin-Heng Guo +1

The direct CP asymmetry in quasi-two-body decays of $B \to (V \to π^{+} π^{-}) P$ is investigated in the perturbative QCD method, where P represents a pseudoscalar me…

CP asymmetry from resonance effect of B meson decay process with $π$ and K final states

Gang Lü, Xi-Liang Yuan, Na-Wang +1

We introduce the new resonance of $V \to K^{+} K^{-}$ $(V = ϕ, ρ, ω)$ , which produces some new strong phase associated with vector meson resonance and thus can cause relatively…

Direct $C P$ violation of three bodies decay process from the resonance effect

Gang Lü, Yan-Lin Zhao, Liang-Chen Liu +1

The physical state of $ρ$ - $ω$ - $ϕ$ mesons can be mixed by the unitary matrix. The decay processes of $ω \to π^{+} π^{-}$ and $ϕ \to π^{+} π^{-}$ are from the isospin sym…

QCD Factorization in $B$ Decays into $ρ π$

X. -H. Guo, O. Leitner, A. W. Thomas

Based on the QCD factorization approach we analyse the branching ratios for the channel $B \to ρ π$ . From the comparisons with experimental data provided by CLEO, BELLE and BABAR we…

Direct CP Violation in $B \to π^{+} π^{-} π$ : Determination of $α$ without discrete ambiguity

O. Leitner, X. -H. Guo, A. W. Thomas

Direct CP violation in the hadronic decays $\Bar{B}^{0} \to π^{+}π^{-} π^{0}$ is investigated near the peak of the $ρ^{0}$ taking into account the effect of $ρ - ω$ mixing. Branchin…

Enhanced direct CP violation in $B^{\pm, 0} \to π^{+} π^{-} K^{\pm, 0}$

O. Leitner, X. -H. Guo, A. W. Thomas

We investigate in a phenomenological way, direct CP violation in the hadronic decays $B^{\pm, 0} \to π^{+} π^{-} K^{\pm, 0}$ where the effect of $ρ - ω$ mixing is included. If $N_{c}^…

Heavy quark distribution functions in heavy baryons

X. -H. Guo, A. W. Thomas, A. G. Williams

Using the Bethe-Salpeter (B-S) equations for heavy baryons Lambda_Q, Sigma_Q, Xi_Q and Omega_Q (Q=b or c), which were established in previous work, we calculate the heavy quark dis…

Enhanced Direct CP Violation in $B^{\pm} \to ρ^{0} π^{\pm}$

X. -H. Guo, O. Leitner, A. W. Thomas

We study direct CP violation in the hadronic decay $B^{\pm} \to ρ^{0} π^{\pm}$ , including the effect of $ρ - ω$ mixing. We find that the CP violating asymmetry is strongly dependent…

X. -H. Guo, A. W. Thomas, A. G. Williams

In the heavy quark limit, the heavy baryons ω_{Q}^{(*)} (ωcould be Σ, Ξor Ωand Q=b or c) are regarded as composed of a heavy quark and an axial vector, light diquark with good spin…
