We present a calculation of thick-wall Coleman-de Luccia (CdL) bounces in the standard model effective potential in a de Sitter background. The calculation is performed including the effect of the bounce backreaction on the metric, which we compare with the case of a fixed de Sitter background, and with similar full-backreaction calculation in a model polynomial potential. The results show that the standard model potential exhibits nontrivial behavior: rather than a single CdL solution, there are multiple (nonoscillating) bounce solutions which may contribute to the decay rate. All the extra solutions found have higher actions than the largest amplitude solution, and thus would not contribute significantly to the decay rate, but their existence demonstrates that CdL solutions in the standard model potential are not unique, and the existence of additional, lower action, solutions cannot be ruled out. This suggests that a better understanding of the appearance and disappearance of CdL solutions in de Sitter space is needed to fully understand the vacuum instability issue in the standard model.
