abstract

We present two-loop renormalization of $\phi^3$-model effective action by using the background field method and cutoff momentum regularization. In this paper, we also study a derivation of the quantum equation of motion and its application to the renormalization.

  1. Three-loop singularity structure for a non-linear sigma model

    hep-th 2025-07 conditional novelty 6.0 of 10

    The three-loop divergent structure of the two-dimensional non-linear sigma model is computed in a coordinate-space cutoff scheme, including the new countervertices and the squared-logarithm part of the renormalization...

  2. Effective actions, cutoff regularization, quasi-locality, and gluing of partition functions

    math-ph 2024-11 conditional novelty 6.0 of 10

    A coordinate-space averaging regularization is shown to be compatible with gluing partition functions on Riemannian manifolds with boundaries.
