Abstract

We calculate critical exponents of chiral Ising,XY and Heisenberg universality classes up to second order in 4 − ϵ expansion. General expressions for any number N of fermionic variables are given and compared with recent extensive 1/N calculation and lattice simulations. The possibility that these new universality classes describe critical phenomena in certain 3D magnetic systems and in finite temperature phase transitions of 3 + 1 dimensional quantum field theories is briefly discussed.
