We considered vacuum decay in the presence of a non-minimal coupling to gravity. We extended the usual thin-wall solution to include the non-minimal coupling and verified its validity by comparison with a full numerical study. We also investigated the implications of a large cosmological constant whose influence on the geometry booststhe tunneling rate. Our results show that the influence of the non-minimal coupling differs significantly between the cases of Minkowski and de Sitter backgrounds which I will describe in details in my talk.
