中文摘要：

最近由CDF合作组和DO合作组测量的Bs质量差△Ms粗略地与标准模型预测值一致，因此这些测量将对限制超出标准模型的新物理信号提供一个机会．考虑 B^0s-B-^0s 混合中的R宇称破缺超对称效应，并用最近△Ms的实验结果去限制树图的R宇称破缺耦合．然后，通过从△舰实验限制得到R宇称破缺耦合的参数空间，显示在Bs宽度差△Гs中的R宇称破缺超对称效应．

英文摘要：

The recent measurements of the Bs mass difference △Ms by the CDF and DФ collaborations are roughly consistent with the Standard Model predictions, therefore, these measurements will afford an opportunity to constrain new physics scenarios beyond the Standard Model. We consider the impact of the Rparity violating supersymmetry in the B^0s-B-^0s mixing, and use the latest experimental results of △Ms to constrain B^0s-B-^0smixing. Then, using the constrained RPV the size of the R-parity violating tree level couplings in the B^0s-B-^0s parameter space from △Ms, we show the R-parity violating effects on the Bs width difference △Гs.
