Journal of High Energy Physics, Vol 2023, Iss 2, Pp 1-37 (2023)
Abstract We employ Padé approximants in the study of the analytic structure of the four-dimensional SU(2) Landau-gauge gluon and ghost propagators in the infrared regime. The approximants, which are model independent, serve as fitting functions for
