Abstract
We note that the emerging features of lepton mixing can be reproduced if, with inverted neutrino mass ordering, both the smallest neutrino mass and the element of the neutrino mass matrix vanish. Then, the atmospheric neutrino mixing angle is less than maximal and the Dirac phase is close to . We derive the correlations among the mixing parameters and show that there is a large cancellation in the effective mass responsible for neutrinoless decay. Three simple seesaw models leading to our scenario are provided.
