夸克质量与强CP破坏
Quark masses and strong CP violation
摘要:
双味QCD涉及三个独立的质量参数,非微扰效应并不普适。这排除了非简并夸克的匹配晶格和微扰结果,并消除了消失的上夸克质量作为强CP问题的可行解决方案。
英文摘要:
Two flavor QCD involves three independent mass parameters for which non-perturbative effects are not universal. This precludes matching lattice and perturbative results for non-degenerate quarks and eliminates a vanishing up quark mass as a viable solution to the strong CP problem.
