DOI: 10.1007/jhep09(2018)069
Abstract: A bstractWe explore the possibility that the semi-leptonic B decay ratios RK*$$ {R}_{K^{\left(*\right)}} $$ which violate μ − e universality are related to the origin of the fermion Yukawa couplings in the Standard Model. Some… read more here.

DOI: 10.1007/jhep11(2018)100
Abstract: A bstractWe construct a model where the Yukawa couplings of the Standard Model (SM) fermions arise from the breaking of a Z2 symmetry and through mixing with a fourth family of vector-like fermions. By adding… read more here.

DOI: 10.1103/physrevd.95.035005
Abstract: We revisit a recent solution to the flavor hierarchy problem based on the paradigm that Yukawa couplings are, rather than fundamental constants, effective low energy couplings radiatively generated by interactions in a hidden sector of… read more here.

DOI: 10.1103/physrevd.98.075007
Abstract: The observation of tt¯h(125) production at the Large Hadron Collider (LHC) is the first direct measurement of the top Yukawa coupling. It opens the window on an extra top Yukawa coupling, ρtt, from a second… read more here.

DOI: 10.1103/physrevd.99.095029
Abstract: We propose a model in which the Yukawa couplings of Higgs doublets are related to the couplings of the chiral fermions to a scalar leptoquark triplet. This is due to their common origin via mixing… read more here.
