Universal mass texture and quark-lepton complementarity

Abstract

Recent measurements of the neutrino and quark mixing angles satisfy the empirical relations called quark-lepton complementarity. This empirical data suggests the existence of a correlation between the mixing matrices of leptons and quarks. In this work, we examine the possibility that this correlation between the mixing angles of quarks and leptons originates in the similar hierarchy of quarks and charged lepton masses and the seesaw mechanism type I that gives mass to the Majorana neutrinos. We asssume that the similar mass hierarchies of charged lepton masses and quark masses allows one to represent all the mass matrices of Dirac fermions in terms of a four zeros Fritzsch texture.
