dc.description.abstract | We study the properties of singular values of mixing matrices embedded within an experimentally
determined interval matrix.We argue that any physically admissible mixing matrix needs to have the property
of being a contraction. This condition constrains the interval matrix, by imposing correlations on its elements
and leaving behind only physical mixings that may unveil signs of new physics in terms of extra neutrino
species. We propose a description of the admissible three-dimensional mixing space as a convex hull over
experimentally determined unitary mixing matrices parametrized by Euler angles, which allows us to select
either unitary or nonunitary mixing matrices. The unitarity-breaking cases are found through singular values
and we construct unitary extensions, yielding a complete theory of minimal dimensionality larger than
3 through the theory of unitary matrix dilations. We discuss further applications to the quark sector. | pl_PL |
