Flavour alignment in multi-Higgs-doublet models

Flavour alignment in multi-Higgs-doublet models

Abstract Extended electroweak scalar sectors containing several doublet multiplets require flavour-aligned Yukawa matrices to prevent the appearance at tree level of unwanted flavour-changing neutral-current transitions. We analyse the misalignment induced by one-loop quantum corrections and explore...
