Disentangling the seesaw mechanism in the left-right model: An algorithm for the general case

Senjanovic and Tello have analyzed how one could determine the neutrino Dirac mass matrix in minimal left-right model, assuming that matrices for light heavy neutrinos be taken as inputs. They provided an analytical solution case symmetry is implemented via a generalized parity this remains unbroken Yukawa sector. We extend work of to which broken In elegant method outlined by breaks down we need adopt numerical approach. Several iterative approaches are described; these found some cases but highly unstable others. A stable, prescriptive algorithm described works all vanishingly small number cases. apply data sets consistent with current experimental constraints on masses mixings. also provide additional context supporting explanations unbroken.
