Renormalization Group Approach to Scalar Theory
arXiv:hep-th/9404086
Abstract
Effective potential for scalar theory is obtained using the exact renormalization group method which includes both the usual one-loop contribution as well as the dominant higher loop effects. Our numerical calculation indicates a breakdown of naive one-loop result for sufficiently large renormalized coupling constant.
