摘要：

The implications of both one loop and gaussian approximation to the effective potential of massless lambdaPHI4 theories are analyzed. By assuming only the unavoidable existence of a regularization scheme which preserves the variational inequality, it is possible to obtain an estimate of the weak coupling beta-function which is remarkably consistent with the Coleman-Weinberg one loop calculation. Both indicate that massless lambdaPHI4 theories are asymptotically free, not in contradiction with any known rigorous result. The consequences of our analysis for the Standard Model of electroweak interactions are briefly illustrated.
