Trimaximal-Cabibbo neutrino mixing: A parametrization in terms of deviations from tri-bimaximal mixing

Understand

In this paper we study a parametrized description of neutrino mixing from a phenomenological point of view.

• We concentrate on the parametrization in terms of higher order corrections to the leading order mixing matrix.
• A method to describe subleading contributions and its applications to tri-bimaximal mixing are discussed.
• We show that mixing matrices similar to tri-bimaximal-Cabibbo mixing can be obtained by straightforward choices of parameters.
