在Tevatron的Bs区寻找新物理

Search for New Physics in the Bs Sector at the Tevatron

Thomas Kuhr

摘要:

虽然B 0和B+介子在B工厂得到了很好的研究,但到目前为止,B 0 s介子的大样本只能在Tevatron中获得。由于B 0 s介子由第二代和第三代夸克组成,它为寻找新的物理效应提供了补充探针。给出了关于衰变B 0 s-> mu+ mu-和B 0 s-> mu+ mu- phi以及B 0 s混合和混合与衰变干涉中的CP破坏的CDF和D 0实验结果。

英文摘要:

While B0 and B+ mesons are well studied at B-factories, large samples of B0s mesons are only available at the Tevatron so far. Since the B0s meson consists of quarks of the second and third generation it provides a complementary probe for searches for new physics effects. Results of the CDF and D0 experiments on the decays B0s -> mu+ mu- and B0s -> mu+ mu- phi as well as on CP violation in B0s mixing and in interference between mixing and decay are presented.
