Exact calculations of vertex $s ˉ γ b$ and $s ˉ Z b$ in the unitary gauge

Lu-sen Wu, Zhen-jun Xiao

In this paper, we present the exact calculations for the vertex $s ˉ γ b$ and $s ˉ Z b$ in the unitary gauge. We found that (a) the divergent- and $μ$ -dependent terms are lef…

The single t-quark productions via the flavor-changing processes in the topcolor-assisted technicolor model at the hadron colliders

Wenna Xu, Xuelei Wang, Zhenjun Xiao

In the framework of topcolor-assisted technicolor(TC2) model, there exist tree-level flavor-changing (FC) couplings which can result in the loop-level FC coupling $t c g$ . Such $t c g$ …

$B_{s (d)}^{0} - B ˉ_{s (d)}^{0}$ mixing and new physics effects in a top quark two-Higgs doublet model

Lin-xia Lü, Zhen-jun Xiao

We calculate the new physics contributions to the neutral $B_{d}^{0}$ and $B_{s}^{0}$ meson mass splitting $Δ M_{d}$ and $Δ M_{s}$ induced by the box diagrams involving the charged-Higgs bosons…

$B \to K K^{*}$ Decays in the Perturbative QCD Approach

Libo Guo, Qian-gui Xu, Zhen-jun Xiao

We calculate the branching ratios and CP-violating asymmetries for $B^0 \to K^{0} \ov K^{*0}$, $\ov K^{0} K^{*0}$, $K^{+} K^{*-}$ , $K^{-} K^{*+}$ , and $B^+\to K^+ \ov K^{*0}$ and $ \ov…

Branching Ratio and CP Asymmetry of $B_{s} \to ρ (ω) K$ Decays in the Perturbative QCD Approach

Zhen-jun Xiao, Xin-fen Chen, Dong-qin Guo

In this paper, we calculate the branching ratios and CP-violating asymmetries for $B_{s} \to ρ^{\pm} K^{\mp}$ , $B_{s} \to ρ^{0} K ˉ^{0}$ and $B_{s} \to ω K ˉ^{0}$ decays in the perturbat…
