n粒子SU（N）形状因子的渐近分解
Asymptotic factorization of n-particle SU(N) form factors
摘要：
研究了1 + 1维SU（N）手征Gross-Neveu模型的高能行为.该模型是可积的，并且几个局部算子（形状因子）的矩阵元是精确已知的。形状因子表现出快度空间聚类，这意味着因子分解，如果一组快度被移动到无穷大。我们用SU（N）模型分析了这一现象。对于几个算子的因式分解公式显式。
英文摘要：
We investigate the high energy behavior of the SU(N) chiral Gross-Neveu model in 1 + 1 dimensions. The model is integrable and matrix elements of several local operators (form factors) are known exactly. The form factors show rapidity space clustering, which means factorization, if a group of rapidities is shifted to infinity. We analyze this phenomenon for the SU(N) model. For several operators the factorization formulas are presented explicitly.
