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.
Speaker Intro
Hrachya Babujian (Babujyan) received his PhD from L. D. Landau Institute of Theoretical Physics in Moscow, where he was PhD student of A.A. Belavin. The Habilitation he get in Yerevan Physics Institute (Alikhanyan National Lab) where he currently holds the title Leading Scientific Researcher. In the 1990’s he was working in Bonn University and Berlin FU where he enjoy the Mathematical Physics group of R. Schrader. He also work in Sao Carlos University (Brazil) in Brookhaven National Lab, Simons Center and Chicago University. H. Babujian’s research interests are in Integrability in 2d statistical models and 1+1 dimensional quantum field theories, 1d spin chains, conformal blocks, form factors and thermodynamics of integrable models. Now his interest is the applications of the exact form factors in 1+3 dimensional lepton-hadron scattering in small Bjorkan x case.
