We present a revised version of the so-called “yukawaon model”, which was proposed for the purpose of a unified description of the lepton mixing matrix UPMNS and the quark mixing matrix VCKM. It is assumed from a phenomenological point of view that the neutrino Dirac mass matrix MD is given with a somewhat different structure from the charged lepton mass matrix Me, although MD=Me was assumed in the previous model. As a result, the revised model predicts a reasonable value sin22θ13∼0.07 with…
