The behavior of the sextic coupling for the scalar field at the intermediate and strong coupling regime
Gino N. J. Ananos
Abstract
We study the behavior of the renormalized sextic coupling at the intermediate and strong coupling regime for the ϕ4 theory defined in d=2-dimension. We found a good agreement with the results obtained by the field-theoretical renormalization-group in the Ising limit. In this work we use the lattice regularization method.
