底部重子

Bottom Baryons

摘要:

最近CDF和D0合作观测到了几个底重子。在这项工作中,我们在重夸克有效场论(HQET)的框架内,使用QCD求和规则方法,对直到$1/m_Q$的底部重子质量进行了系统的研究。提取的底重子重二重态之间的色磁分裂与实验数据符合得很好。

英文摘要:

Recently CDF and D0 collaborations observed several bottom baryons. In this work we perform a systematic study of the masses of bottom baryons up to $1/m_Q$ in the framework of heavy quark effective field theory (HQET) using the QCD sum rule approach. The extracted chromo-magnetic splitting between the bottom baryon heavy doublet agrees well with the experimental data.
