Abstract

Astronomy & Astrophysics Physical Sciences Physics Physics, Nuclear Physics, Particles & Fields Science & Technology
We study the non-linear gap equation for the self energy of technifermions in a general gauge. The equation is solved numerically. The gauge sensitivity of the large momentum behaviour of the self energy leads to substantial gauge dependence in the estimate of the fermion condensate vacuum expectation value. The technipion coupling constant displays moderate gauge dependence.
