Can the nondiagonal charged-lepton mass matrix improve the tripartite neutrino mixing?

Abstract

It is shown that the off-diagonal corrections in a realistic charged-lepton mass matrix, introduced previously by the author, cannot improve much the tripartite neutrino mixing. In fact, $s_{12}^2=1/3-0.005=0.328\simeq 1/3$ for $s_{12}^2$ improved in this way, while $s_{12\exp }^2=0.314=1/3-0.019$ for the central value of experimental $s_{12\exp }^2$.
