Constraints on the Aligned Two-Higgs-Doublet Model and CP violation

The Aligned Two-Higgs-Doublet Model (A2HDM) [Pich A. and Tuzon P. Yukawa Alignment in the Two-Higgs-Doublet Model. Phys. Rev. D80, (2009), 091702. 0908.1554] describes a particular way of enlarging the scalar sector of the Standard Model (SM), with a second Higgs doublet which is aligned to first the one in flavour space. This implies the absence of flavour-changing neutral currents (FCNCs) at tree level and the presence of three complex parameters. Within this general approach, we analyze the charged Higgs phenomenology, including CP asymmetries in the K and B systems [Jung M., Pich A. and Tuzon P. Charged-Higgs phenomenology in the Aligned two-Higgs-doublet model1006.0470].
