Status of the aligned two-Higgs-doublet model confronted with the Higgs data

Imposing the theoretical constraints from vacuum stability, unitarity and perturbativity as well as the experimental constraints from the electroweak precision data, flavor observables and the non-observation of additional Higgs at collider, we study the implications of available Higgs signals on a two-Higgs-doublet model with the alignment of the down-type quarks and charged lepton Yukawa coupling matrices. Compared to the four traditional types of two-Higgs-doublet models, the model has two additional mixing angles theta(d) and theta(l) in the down-type quark and charged lepton Yukawa interactions. We find that the mixing angle theta(d) can loose the constraints on sin(beta - alpha), tan beta and m(H)+/- sizably. The model can provide the marginally better fit to available Higgs signals data than SM, which requires the Higgs couplings with gauge bosons, u (u) over bar and d (d) over bar d to be properly suppressed, and favors (1 < theta(d) < 2, 0.5 < theta(l) < 2.2) for m(h) = 125.5GeV and (0.5 < theta(d) < 2, 0.5 < theta(l) < 2.2) for m(H) = 125.5GeV. However, these Higgs couplings are allowed to have sizable deviations from SM for (m(h) = 125.5GeV, 125.5 = m(H) = 128GeV) and (125GeV = m(h) = 125.5GeV, m(H) = 125.5GeV).
