@inproceedings{Law2021OnTC, title={On the Charged and CP-violating Kink Solutions in the Two Higgs Doublet Model}, author={Kai Hong Law and Apostolos Pilaftsis}, year={2021} }

Minimal extensions of the Standard Model (SM), such as the so-called Two Higgs Doublet Model (2HDM), can possess several accidental discrete symmetries whose spontaneous breakdown in the early universe usually lead to the formation of domain walls. We extend an earlier work [32] on this topic by studying in more detail the analytic properties of electrically charged and CP-violating kink solutions in the Z2symmetric 2HDM. We derive the complete set of equations of motion that describe the 1D…

We find that a Z-string is stable in a wide range of parameter space of the two Higgs doublet model due to a split into a pair of two topological Z-strings with fractional Z fluxes. This…
