How can CP violation in the neutrino sector be large in a $2\leftrightarrow 3$ symmetric model?

Abstract

Based on a neutrino mass matrix model in which a 2-3 symmetry is only broken by a phase parameter, it is investigated how the lepton mixing matrix can deviate from the so-called tribimaximal mixing under a condition that CP is maximally violated.
