摘要:

本文讨论了标量Bs 0 ~*(5725)和轴向Bs 1 ~*(5778)底奇异介子分别作为B K和B ~* K介子的强子分子束缚态的可能解释。用唯象拉格朗日方法分析了强Bs 0 * 到Bs pi 0,Bs 1到Bs* pi 0和辐射Bs 0 * 到Bs* γ,Bs 1到Bs γ,Bs 1到Bs* γ,Bs 1到Bs 0 * γ衰变.我们预测的衰变特性:有效耦合和衰变宽度。

英文摘要:

We discuss a possible interpretation of the scalar Bs0*(5725) and axial Bs1(5778) bottom-strange mesons as hadronic molecules - bound states of B K and B* K mesons, respectively. Using a phenomenological Lagrangian approach we analyze the strong Bs0* to Bs pi0, Bs1 to Bs* pi0 and the radiative Bs0* to Bs* gamma, Bs1 to Bs gamma, Bs1 to Bs* gamma, Bs1 to Bs0* gamma decays. We give predictions for the decay properties: effective couplings and decay widths.
