Constraining general two Higgs doublet models by the evolution of Yukawa couplings

Summary, in English

We analyse the constraints of the general two Higgs doublet models by evolving the Yukawa coupling constants to high energy under renormalization group. We consider the appearance of a Landau pole or large off-diagonal Yukawa couplings which cause tree level flavour changing neutral currents. Our study shows the latter condition can be used to answer how much Z
symmetry breaking can be allowed in a given 2HDM model.
