摘要：

We derive an exact expression for the static bounce solution for 4 theory with broken symmetry. We also propose a new approach to compute a nontrivial real contribution to the generating functional around a classical bounce-type solution avoiding problems due to the presence of a negative eigenvalue. We get this by using the arbitrariness in the mass scale of Wick ordering for the 4 model in dimension d=1+1. © 1990 The American Physical Society.
