Tribimaximal mixing

Tribimaximal mixing is a specific postulated form for the Pontecorvo–Maki–Nakagawa–Sakata (PMNS) lepton mixing matrix U. Tribimaximal mixing is defined by a particular choice of the matrix of moduli-squared of the elements of the PMNS matrix as follows: This mixing is presently excluded by experiment at the level of 5σ. The tribimaximal mixing form was compatible with much older neutrino oscillation experiments and may be used as a zeroth-order approximation to more general forms for the PMNS matrix, for example those which are also consistent with the data. In the PDG convention for the PMNS matrix, tribimaximal mixing may be specified in terms of lepton mixing angles as follows: The above prediction has been falsified experimentally, because θ13 was found to be nontrivial, θ13 =8.5°. A non-negligible value of θ13 has been foreseen in certain theoretical schemes that were put forward before tribimaximal mixing and that supported a large solar mixing, before it was confirmed experimentally (these theoretical schemes do not have a special name, but for the reasons explained above, they could be called pre-tribimaximal or also non-tribimaximal). This situation is not new: also in the 1990s, the solar mixing angle was supposed to be small by most theorists, until KamLAND proved the contrary to be true. (Wikipedia).
