An. Vasilev et As. Stepanenko, THE 1 N EXPANSION IN THE GROSS-NEVEU MODEL - CONFORMAL BOOTSTRAP CALCULATION OF THE EXPONENT 1/NU TO THE ORDER 1/N(2)/, Theoretical and mathematical physics, 97(3), 1993, pp. 1349-1354
The critical exponent 1/nu (dimensions of temperature) in the U(N)-sym
metric Gross-Neveu model is calculated to the order 1/n2 (n = N tr 1)
for arbitrary dimension of space.
