Description
Popular lepton mixing models are in clear disagreement with the recent oscillation observation of nonzero $\theta_{13}$. We show that by supplementing these models by a single perturbation the conflict can be addressed. Starting from a point where $\theta_{13}$ is zero and the first two neutrino mass eigenstates are degenerate leading to no solar splitting initially, we device a perturbation that splits the degeneracy as well as generates nonzero $theta_{13}$ in one stroke thereby relating them. A neutrino mass model to justify the origin of the mass matrices will also be presented that will demonstrate the execution of the procedure.
