Query: Phase structure of Topologically massive gauge theory with fermion   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.
