Vs. Alves et al., Perturbative Gross-Neveu model coupled to a Chern-Simons field: A renormalization group study - art. no. 045002, PHYS REV D, 5904(4), 1999, pp. 5002
In 2+1 dimensions, for low momenta, using dimensional renormalization we st
udy the effect of a Chern-Simons field on the perturbative expansion of fer
mions self-interacting through a Gross-Neveu coupling. For the case of just
one fermion field, we verify that the dimension of operators of canonical
dimension lower than three decreases as a function of the Chern-Simons coup
ling. [S0556-2821(98)07224-5].
