  • 基于LHCb、Tevatron以及D0实验组关于中性Bs介子混合的最新实验结果, 12s中有可能存在大的新物理贡献, 我们在代非普适Z'模型下对Bs-Bs混合进行了研究. 假定Z'玻色子不仅对非对角矩阵元M12s有贡献, 还考虑了由树图交换Z'玻色子所导致的b scc算符对非对角矩阵元12s的贡献. 结果表明: 在Ms, s和Bd J/ KS衰变的间接CP不对称这些物理可观测量的联合限制下, 实验值afss不到解释. 因此, 在对代非普适Z'模型假定下, 不能同时对所有中性Bs介子混合观测量给出解释. 伴随着LHCb以及未来的超级B工厂的运行,尤其是对CP不对称afss的测量, 期望这一问题将得到解答.
    Motivated by recent measurements of the neutral Bs-meson mixing, obtained by LHCb group and the Tevatron, and the possibility to have sizable NP effects in 12s, we revisit the Bs mixing in a family non-universal Z' model. We assume that the Z' boson contributes to the off-diagonal element M12s and also to the off-diagonal element 12s via tree-level Z'-induced b scc operators. We find that, with the constraints from Mss and the indirect CP asymmetry in BdJ/KS imposed, the present measured 1 experimental ranges for afss could not be reproduced. Thus, such a specific model could not simultaneously explain the present data on Bs mixing. It is expected that with the operation of the LHCb group and the future super B experiments, more accurate measurements, especially of the flavour-specific CP asymmetries, could shed light on the issue.
