Description

The alignment in flavour space of the Yukawa matrices of a general two-Higgs-doublet model (THDM) results in the absence of tree-level flavour-changing neutral currents. In addition to the usual masses and mixings, the aligned Yukawa structure is parametrized by three complex numbers which are potential new sources of CP violation. For particular values of these complex parameters all Z2-type models are recovered. One of the most distinctive features of the THDM's is the presence of a charged Higgs, whose phenomenology is also showed in this talk finding important bounds on the Aligned two-Higgs-doublet model (ATHDM) parameter space.
