Abstract
We discuss constraints from the stability of the electroweak vacuum in BSM models with extended scalar sectors. We present an efficient and reliable method to obtain vacuum stability constraints at tree-level based on the straight path approximation for the bounce action. In the MSSM, we obtain vacuum stability constraints on a benchmark scenario that are complementary to experimental limits and illustrate the reliability of our method. In a parameter scan of the type I N2HDM, we show a direct constraint from vacuum stability on the possible values for the diphoton rate of the 125 GeV Higgs boson.
