Three-Loop Effective Potential of O(N) Theory
J. -M. Chung, B. K. Chung
The three-loop effective potential of the massless O(N) theory is calculated analytically using techniques of dimensional regularization. We see a complete agreement between…

Renormalization conditions and the effective potential of the massless phi^4 theory
J. -M. Chung, B. K. Chung
We point out that there is a missing portion in the two-loop effective potential of the massless O(N) phi^4 theory obtained by Jackiw in his classic paper, Phys. Rev. D 9, 1686 (19…
