B s → μ + μ − in a two-Higgs-doublet model with flavour-changing up-type Yukawa couplings

Abstract We present a Two-Higgs-Doublet Model in which the structure of the quark Yukawa matrices is governed by three spurions breaking the flavour symmetries of the quark Yukawa sector. The model naturally suppresses flavour-changing neutral current (FCNC) amplitudes in the down-type sector, but p...
