Neutrino masses and neutrino mixing

open access: yesNuclear Physics B - Proceedings Supplements, 2006
We review the current (summer 2005) status of neutrino mass and mixing parameters, as emerging from a phenomenological analysis of world neutrino oscillation and non-oscillation data, performed within the standard three-neutrino mixing framework.

Limits on the mixing of tau neutrino to heavy neutrinos

open access: yesPhysics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physics, 2002
Limits at 90 % c.l. on the square of the mixing strength |U_tau4|^2 between nu_tau and a mostly isosinglet heavy neutrino with mass in the range 10-290 MeV/c^2 are reported. The results were derived using the negative result of a search for neutral particles decaying into two electrons conducted by the CHARM collaboration in a neutrino beam dump ...

Constraints on non-unitary neutrino mixing in light of atmospheric and reactor neutrino data

open access: yesJournal of High Energy Physics
While the origin of neutrino masses remains unknown, several key neutrino mass generation models result in a non-unitary three-neutrino mixing matrix. To put such models to test, the deviations of the mixing matrix from unitarity can be measured directly

Physics Potential of a Long Baseline Neutrino Oscillation Experiment Using J-PARC Neutrino Beam and Hyper-Kamiokande [PDF]

open access: yes, 2015
39 pages, 26 figures, submitted to PTEPHyper-Kamiokande will be a next generation underground water Cherenkov detector with a total (fiducial) mass of 0.99 (0.56) million metric tons, approximately 20 (25) times larger than that of Super-Kamiokande.

Neutrino-4 anomaly: Oscillations or fluctuations?

open access: yesPhysics Letters B, 2021
We present a deep study of the Neutrino-4 data aimed at finding the statistical significance of the large-mixing short-baseline neutrino oscillation signal claimed by the Neutrino-4 collaboration at more than 3σ. We found that the results of the Neutrino-

Phenomenology of Trimaximal Mixing with One Texture Equality

open access: yesAdvances in High Energy Physics, 2022
We study neutrino mass matrices with one texture equality and the neutrino mixing matrix having either its first (TM1) or second (TM2) column identical to that of the tribimaximal mixing matrix.

Neutrino-Modulino Mixing [PDF]

open access: yesPhysical Review Letters, 1997
We suggest the existence of a light singlet fermion, $S$, which interacts with observable matter only via a Planck mass suppressed interaction: $\sim m_{3/2}/M_P$, where $m_{3/2}$ is the supergravity gravitino mass. If the mass of the singlet equals $\sim m_{3/2}^2/M_P$, then $ν_e \to S$ resonance conversion solves the solar neutrino problem or leads ...

Displaced vertex signatures of a pseudo-Goldstone sterile neutrino

open access: yesJournal of High Energy Physics, 2021
Low-scale models of neutrino mass generation often feature sterile neutrinos with masses in the GeV-TeV range, which can be produced at colliders through their mixing with the Standard Model neutrinos.
