DOI: 10.1007/jhep08(2018)195
Abstract: A bstractContrary to the standard model that does not admit topologically nontrivial solitons, two Higgs doublet models admit topologically stable vortex strings and domain walls. We numerically confirm the existence of a topological Z-string confining… read more here.
