One-loop inert and pseudo-inert minima

Abstract

We analyse the differences between inert and pseudo-inert vacua in the 2HDM, both at tree-level and one-loop. The validity of tree-level formulae for the relative depth of the potential at both minima is studied. The one-loop analysis shows both minima can coexist in regions of parameter space forbidden at tree-level.
