夸克间微扰势的相对论性非微扰修正 RELATIVISTIC NON-PERTUBATIVE CORRECTIONS TO THE PERTURBATIVE POTENTIAL BETWEEN QUARKS 刘觉平 Liu Jueping 1 first-author 武汉大学物理学系 武汉大学物理学系 Department of Physics, Wuhan University Department of Physics, Wuhan University 计算了胶子凝聚与夸克凝聚对于微扰量子色动力学中夸克与夸克之间的相互作用势的非微扰修正的相对论形式及其非相对论形式展开．由于超出了一般的非相对论近似，一些新形式的自旋－自旋相互作用项、自旋－轨道相互作用项出现在势的表达式中． We calculated the non-perturbative corrections due to the gluon and quark condensates for the perturbative QCD potential between quarks in a relativistic form, then an expansion in a non-relativistic form is made.Some new spin-spin interaction terms and spinorbit interaction ones appear in the expression of the potontial because of going beyond the usual non-relativistic approximation. 量子色动力学 夸克互作用势 非相对论形式展开 quantum chromodynamics quark potential expansion in a non-relativistic form O572.3 国家自然科学基金(61672102) 1994-04-01 2021-04-01 4
