强子物理学在CLEO-c

Hadronic Physics at CLEO-c

M. R. Shepherd

摘要:

粲偶素系统提供了一个探索强子物理中各种各样的主题的机会。对cc-bar态的性质和跃迁的研究使我们深入了解相对论性和非微扰QCD效应。同时,对粲偶素衰变的研究也是了解胶子动力学和胶球混合在轻夸克态产生中的作用的一个窗口。利用CLEO-cpsi(2S)数据样本的初步结果的收集,包括两个体的分支的chicJ衰变的分数,hc质量的精确测量,和结果的阻碍M1过渡:psi(2S)-> gamma eta_c。

英文摘要:

The charmonium system provides an opportunity to explore a wide variety of topics in hadronic physics. Studies of the properties of and transitions among cc-bar states yield insight into relativistic and non-perturbative QCD effects. At the same time, studies of the decays of charmonium states are a window into gluon dynamics and the role of glueball mixing in the production of light quark states. A collection of preliminary results utilizing the full CLEO-c psi(2S) data sample is presented including two-body branching fractions of chi_cJ decays, a precision measurement of the h_c mass, and results on the hindered M1 transition: psi(2S) -> gamma eta_c.
