The Two-Higgs-Doublet Model (2HDM) is an extension of the Standard Model of particle physics that incorporates two Higgs doublets instead of just one. In the Standard Model, a single Higgs doublet is responsible for the electroweak symmetry breaking mechanism, which gives mass to the W and Z gauge bosons and fermions.
