Three lectures on the Curci-Ferrari model
arXiv:2403.10702
Abstract
In these lectures, we review the status of the Curci-Ferrari model as a phenomenological approach to Landau gauge-fixed YM theories in the infrared. More precisely, after discussing some of the general properties of the model, we explain in full detail the evaluation of the one-loop two-point correlators that allowed for a successful comparison to the corresponding Landau-gauge lattice data. We also review the renormalization group flow of the model which controls its fate at high and low momentum scales.
