低能QCD和强子物理学的若干挑战

Selected challenges in low-energy QCD and hadron physics

Wolfram Weise

摘要:

本文简要介绍了低能QCD的三个基本问题:第一,自发手征对称性破缺的Nambu-Goldstone方案是否成立;第二,QCD中手征和解除禁闭交叉跃迁是否存在动力学纠缠;第三,关于低温和非零重子密度下QCD相图的知识现状。这三个主题作为关键词被注入到一个小组讨论在施拉德明学校在QCD的挑战。下面的说明反映了讨论的风格和特点,但并不要求完整。

英文摘要:

This presentation briefly addresses three basic issues of low-energy QCD: first, whether the Nambu-Goldstone scenario of spontaneous chiral symmetry breaking is well established; secondly, whether there is a dynamical entanglement of the chiral and deconfinement crossover transitions in QCD; and thirdly, what is the status of knowledge about the phase diagram of QCD at low temperature and non-zero baryon density. These three topics were injected as key words into a panel discussion at the Schladming school on Challenges in QCD. The following exposition reflects the style and character of the discussions, with no claim of completeness.
