摘要：

The Standard Model predicts a large width difference in the B-s system. New physics can contribute significantly to the mass difference. If this contribution is CP violating, this will always result in a reduction of the width difference. The analyses of measurements of the width difference using B-s decays into CP eigenstates have to be modified in the presence of new physics. We discuss how the width difference and the new CP violating phase in B-s mixing can be measured.
