传统高能e+e－→hadrons事例产生器普遍采用大Nc近似,使色单态链产生几率达到100%而色分离态几率为0.本文在Nc=3的真实情况下,研究了干涉项中颜色部分和动量部分的来源及性质后发现,对e+e－→qq+ng部分子末态中胶子数2,3,干涉项使色单态链产生几率进一步下降到67%,58%,而n=2时的色分离态几率则增大至不考虑干涉项的2倍.由上推断当胶子数n更大时色单态链几率将远小于1,色分离态...

Lund模型中多部分子的动量分布是由PQCD得出,而这些部分子间的色弦结构则另外由唯象模型指派.从最近发展的e+e－→m(qq)+ng矩阵元递归形式,找出其颜色部分的等效哈密顿量Hc,研究了Hc矩阵元的基本性质,作为从PQCD统一研究多部分子间颜色组态及色相互作用的基础.
qq+ng多部分子体系的色单态集
色单态 完备集 部分子 色弦组态
2009/6/2
从严格的SUc(3)对称,分析qq+ng多部分子体系的色单态集,研究了各类色单态中部分子间的色弦组态.计算发现随n的增加,与Lund CD模型中性质对应的单态色弦几率迅速减少,而与胶子球性质相似的单态集团的比例急速增多,它与αs无关,直观表现为集体效应.
