摘要：In the light of latest neutrino oscillation data, we have investigated the one-zero Majorana neutrino mass matrix with zero sum condition of mass eigenvalues in the flavor basis, where charged lepton mass matrix is diagonal. Among the six possible one-zero cases, it is found that only five can survive the current experimental data, while case with (1, 1) vanishing element of is ruled out, if zero trace condition is imposed at confidence level (CL). Numerical and some approximate analytical results are presented.
