Abstract: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.
