Search for New Physics in the Bs Sector at the Tevatron

Abstract

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.
