PHASE TRANSITION COUPLINGS IN U(1) and <font>SU</font>(N) REGULARIZED GAUGE THEORIES
Using a 2-loop approximation for $\beta$-functions, we have considered the corresponding renormalization group improved effective potential in the Dual Abelian Higgs Model (DAHM) of scalar monopoles and calculated the phase transition (critical) couplings in U(1) and SU(N) regularized gauge theories. In contrast to our previous result $\alpha_{crit} \approx 0.17$, obtained …
