Working towards a gauge-invariant description of the Higgs model: from local composite operators to spectral density functions
D. M. van Egmond
We analyze different BRST invariant solutions for the introduction of a mass term in Yang-Mills (YM) theories. First, we analyze the non-local composite gauge-invariant field $A^h_…

On a renormalizable class of gauge fixings for the gauge invariant operator
M. A. L. Capri, D. M. van Egmond, G. Peruzzo +5
The dimension two gauge invariant non-local operator , obtained through the minimization of along the gauge orbit, allows to introduce a non-local ga…
