Title: 
Hybrid neutrino masses and $\theta_{13}$
Abstract: 
It is useful to write the neutrino mass matrix in terms of the eigenvectors of the lepton mixing matrix. In terms of this decomposition, the neutrino mass matrix can be seen as originating from a tribimaximal dominant structure with small departures required by the reactor mixing angle. Such a structure arises very naturally in cases with more than one mechanism responsible for neutrino masses - "hybrid seesaw".
