Abstract

Multi-field tunneling from false vacuum at the beginning of slow-roll inflation is fa- vored in the picture of string-landscape. We investigate the multi-field tunneling using the method of instanton with gravity. We find multi-field instanton solutions in certain classes of potential numerically as well as perturbatively. Then we study the nature of the obtained instantons.
