Journal of High Energy Physics. ISSN 1029-8479. N.º 4 (2020), pp. 1-321029-8479http://hdl.handle.net/10400.21/12717We analyze the vacuum structure of the one-loop effective potential in the two Higgs doublet model. We find that electroweak-breaking vacua can coexist with charge breaking ones, contradicting a theorem valid at tree-level. We perform a numerical analysis of the model and supply explicit parameter values for which charge-breaking vacua can be the global minimum of the theory, and deeper than charge-preserving ones.engHiggs PhysicsBeyond Standard ModelSpontaneous Symmetry Breakingjournal article10.1007/JHEP04(2020)125
