Three-loop functions for a quartic model with a cutoff
arXiv:2603.21758
Abstract
This paper presents numerical values for auxiliary integrals and coefficients of the beta function in the three-loop approximation for a four-dimensional model with a quartic interaction, using a special type of regularization function. The values are compared to previously obtained results.
