    1414The two-Higgs-doublet model (2HDM) has been extensively studied for more than twenty years now, even though it has often been only considered as the scalar sector of some larger model, like the MSSM or some Little Higgs models for example. The general 2HDM considered here already displays by itself an interesting phenomenology that justifies its study like, for example, new sources of CP violation in scalar-scalar interactions, tree-level flavour changing neutral currents (FCNC's) due to non diagonal Yukawa interactions, or a light pseudoscalar state and unusual Higgs decays
