Fabio Siringo, Luca Marotta
TL;DR
This paper develops a non-perturbative effective model for the Higgs sector of the Standard Model, using a scalar theory and Gaussian Effective Potential, aligning well with lattice simulations at strong coupling.
Contribution
It introduces a non-perturbative scalar model for the Higgs sector with renormalized couplings derived from the Gaussian Effective Potential, bridging analytical and lattice approaches.
Findings
Good agreement with strong coupling lattice simulations
Renormalized couplings derived from Gaussian Effective Potential
Effective model captures non-perturbative Higgs dynamics
Abstract
A non-perturbative effective model is derived for the Higgs sector of the standard model, described by a simple scalar theory. The renormalized couplings are determined by the derivatives of the Gaussian Effective Potential that are known to be the sum of infinite bubble graphs contributing to the vertex functions. A good agreement has been found with strong coupling lattice simulations when a comparison can be made.
