We study the stability of neutral electroweak vacua in two Higgs doublet models, and calculate the lifetime of these states when the parameters are such that they are false vacua. As the two Higgs doublet model is invariant under a sign change of both doublets, degenerate true vacua exist. It is shown that this degeneracy, despite the fact that each of these minima locally describes the same physics, can immensely affect their lifetime. We apply these calculations to the parameter space of the models which is allowed by recent LHC searches, and infer combinations of parameters which should be excluded on grounds of a tunneling time inferior to the age of the universe.

Fate of Metastable Vacua in the Type-II Two-Higgs Doublet Model
In the Type-II two-Higgs-doublet model, once next-to-leading-order unitarity, perturbativity and current data are imposed, the electroweak vacuum remains the global minimum among neutral vacua at tree level and one lo...

Vacuum Instability and False Vacuum Decay Induced by Domain Walls in the N2HDM
Domain walls in the N2HDM can erase the barrier around the electroweak vacuum, making long-lived metastable vacua decay classically and excluding parameter points previously considered viable.
