Abstract

We formulate the conformal bootstrap approach to four--fermion theory at its strong coupling fixed point in dimensions 2<d<42<d<4. We present a solution of the bootstrap equations in the five--vertex approximation. We show that the bootstrap approach gives a particularly simple way to obtain next to leading order corrections to critical exponents in the large NN expansion and present the values of the anomalous dimensions of the fermion field ψ\psi and the composite ψˉψ\bar\psi\psi to order 1/N21/N^2.
