The behavior of the sextic coupling for the the three-dimensional ${\varphi }^4$ theory

Abstract

In this work we use the lattice regularization method to study the behavior of the six point renormalized coupling constant defined at zero momentum for the three-dimensional ${\varphi }^4$ theory in the intermediate and strong coupling domain. The result is in good agreement with the corresponding study in the Ising limit.
