The theory on the lattice: effective potential and triviality
arXiv:hep-lat/9709057 · doi:10.1016/S0920-5632(97)00856-6
Abstract
We compute numerically the effective potential for the theory on the lattice. Three different methods were used to determine the critical bare mass for the chosen bare coupling value. Two different methods for obtaining the effective potential were used as a control on the results. We compare our numerical results with three theoretical descriptions. Our lattice data are in quite good agreement with the ``Triviality and Spontaneous Symmetry Breaking'' picture.
