Phase structure of Topologically massive gauge theory with fermion

Published 2010-02-28, updated 2010-03-12Version 2

Using Bloch-Nordsieck approximation fermion propagator in 3-dimensional gauge theory with topological mass is studied. Infrared divergence of Chern-Simon term is soft,which modifies anomalous dimension. In unquenched QCD with 2-component spinor anomalous dimension has fractional value,where order parmeter is divergent.

Comments: 3 pages,Latex,no figures,for the proceedings of strong coupling gauge theory.typos corrected. anomalous dimension is corrected.
