Leptonic mixing angle ${\theta }_{13}$ and ruling out of minimal texture for Dirac neutrinos

Abstract

Implications of recently measured leptonic mixing angle ${\theta }_{13}$ as well as the other two mixing angles have been examined for Fritzsch-like mass matrices with minimal texture for Dirac neutrinos. Interestingly, the existing data seems to rule out this texture specific case of Dirac neutrinos for normal, inverted hierarchy as well as degenerate scenario of masses.
