重B强子的性质

Properties of Heavy B Hadrons

Manfred Paulini

摘要:

我们回顾了最近对重B强子态的测量,包括B c介子的质量和寿命以及激发B态(B**,Bs**)。讨论了Bs介子在Bs -> J/Psi Phi衰变中的寿命、寿命差δ_Gamma/Gamma和CP破坏等性质。本文还总结了底重子(包括Lambda_b重子、Sigma_b重子、Xi_b和Omega_b重子)质量和寿命的新测量结果。

英文摘要:

We review recent measurements of heavy B hadron states including masses and lifetimes of the Bc meson as well as excited B states (B**, Bs**). We discuss properties of the Bs meson such as lifetime, lifetime difference delta_Gamma/Gamma and CP violation in Bs -> J/Psi Phi decays. We also summarize new measurements of the masses and lifetimes of bottom baryons including the Lambda_b baryon, the Sigma_b baryon states as well as the Xi_b and Omega_b baryons.
