The ν-Tamari Lattice via ν-Trees, ν-Bracket Vectors, and Subword Complexes

Large ν μ → ν τ and ν e → ν τ transitions in short - baseline experiments ?

Considering four-neutrino schemes of type 3+1, we identify four small regions of the neutrino mixing parameter space compatible with all data. Assuming a small mixing between the sterile neutrino and the isolated mass eigenstate we show that large νμ → ντ and νe → ντ transitions are predicted in short-baseline experiments and could be observed in the near future in dedicated experiments. We dis...

Maximal ν μ − ν τ Mixing

The naturalness of maximal mixing between myon-and tau-neutri-nos is investigated. A spontaneously broken nonabelian generation symmetry can explain a small parameter which governs the deviation from maximal mixing. In many cases all three neutrino masses are almost degenerate. Maximal ν µ − ν τ-mixing would indicate that the leading contribution to the light neutrino masses arises from the exp...

Geometry of ν-Tamari lattices in types A and B

In this extended abstract, we exploit the combinatorics and geometry of triangulations of products of simplices to reinterpret and generalize a number of constructions in Catalan combinatorics. In our framework, the main role of “Catalan objects” is played by (I, J)-trees: bipartite trees associated to a pair (I, J) of finite index sets that stand in simple bijection with lattice paths weakly a...

Discriminating between ν μ ↔ ν τ and ν μ ↔ ν sterile in atmospheric ν μ oscillations with the Super – Kamiokande detector

Discriminating between ν µ ↔ ν τ and ν µ ↔ ν sterile in atmospheric ν µ oscillations with the Super–Kamiokande detector. Abstract. A strong body of evidence now exists for atmospheric ν µ disappearance oscillations. Such disappearance could be explained by oscillations to either ν τ or a " sterile " neutrino (ν s). Super–Kamiokande uses three different methods to distinguish between these two s...
