On a renormalizable class of gauge fixings for the gauge invariant operator $A_{\min }^2$

M. A. L. Capri, D. M. van Egmond, G. Peruzzo +5

The dimension two gauge invariant non-local operator $A_{\min }^2$, obtained through the minimization of $\int d^{4}x{A}^2$ along the gauge orbit, allows to introduce a non-local ga…
