Exact form factors of the SU(N) Gross-Neveu model and 1/N expansion

Understand

The general SU(N) form factor formula is constructed.

• Exact form factors for the field, the energy momentum and the current operators are derived and compared with the 1/N-expansion of the chiral Gross-Neveu model and full agreement is found.
• As an application of the form factor approach the equal time commutation rules of arbitrary local fields are derived and in general anyonic behavior is found.
