If leptonic unitarity is violated by new physics at an energy scale much lower than the electroweak scale, which we call low-scale unitarity violation, it has different characteristic features from those expected in unitarity violation at high-energy scales. They include maintaining flavor universality and absence of zero-distance flavor transition. We present a framework for testing such unitarity violation at low energies by neutrino oscillation experiments. Starting from the unitary 3 active plus N (arbitrary positive integer) sterile neutrino model we show that by restricting the active-sterile and sterilesterile neutrino mass squared differences to 0.1 eV 2 the oscillation probability in the (3 + N ) model becomes insensitive to details of the sterile sector, providing a nearly modelindependent framework for testing low-scale unitarity violation. Yet, the presence of the sterile sector leaves trace as a constant probability leaking term, which distinguishes lowscale unitarity violation from the high-scale one. The non-unitary mixing matrix in the active neutrino subspace is common for the both cases. We analyze how severely the unitarity violation can be constrained in ν e -row by taking a JUNO-like setting to simulate medium baseline reactor experiments. Possible modification of the features of the (3 + N ) model due to matter effect is discussed to first order in the matter potential.

“…Neutrino flavor oscillations [26] represent a viable solution to the so-called solar neutrino problem [27] and to the atmospheric neutrino anomaly [28]. This phenomenon can also be probed at accelerators [29][30][31][32][33][34] and reactors [35][36][37][38]. The flavor survival probability of a neutrino with energy E ν , at a distance L from the source is…”

Test of non-standard neutrino properties with the BOREXINO source experiments

We calculate the event rates induced by high-intensity radioactive sources of ν e ( 51 Cr) and ofν e ( 90 Sr), to be located near the BOREXINO detector. Calculations are performed both in the standard case and assuming non-standard properties of neutrinos, including flavor oscillations, neutrino electromagnetic interactions, and deviations from the standard vector and axial couplings in the ν e -e interaction. It is shown that, in some cases, the current limits on non-standard neutrino properties can be significantly improved.

We review previous work on neutrino mass textures in gauge theories. Such textures may arise as a result of flavour symmetries. In a given theory, it is possible to give a classification of heavy Majorana neutrino mass matrices, assuming the Dirac masses of the neutrinos to be of the same form as the ones of the up-quarks. Heavy Majorana neutrino mass matrices leading to large neutrino mixing, are tabulated as an example. Such solutions are now of interest, in the light of the Super-Kamiokande data.
