PT Journal AU Rodejohann, W Valle, JWF TI Symmetrical parametrizations of the lepton mixing matrix SO Physical Review D JI Phys. Rev. D PY 2011 BP 073011 EP 6pp VL 84 IS 7 DI 10.1103/PhysRevD.84.073011 LA English AB Advantages of the original symmetrical form of the parametrization of the lepton mixing matrix are discussed. It provides a conceptually more transparent description of neutrino oscillations and lepton number violating processes like neutrinoless double beta decay, clarifying the significance of Dirac and Majorana phases. It is also ideal for parametrizing scenarios with light sterile neutrinos. ER
