Higgs couplings to fermions: 2HDM with MFV

A bstractWe clarify several subtleties concerning the implementation of minimal flavor violation (MFV) in two Higgs doublet models. We derive all the exact and approximate predictions of MFV for the neutral scalar (h, H, A) Yukawa couplings to fermions. We point out several possible tests of this framework at the LHC.
