Neutrino oscillation prospects with a dual-baseline beam from BNL to SNOLAB and SURF

Journal of High Energy Physics
The Electron-Ion Collider (EIC) is a next-generation accelerator primarily designed to study the internal structure of nucleons through high-precision electron-hadron collisions.

Flavour-symmetric type-II Dirac neutrino seesaw mechanism

Physics Letters B, 2018
We propose a Standard Model extension with underlying A4 flavour symmetry where small Dirac neutrino masses arise from a Type-II seesaw mechanism. The model predicts the “golden” flavour-dependent bottom-tau mass relation, requires an inverted neutrino ...

Neutrino mixing and discrete symmetries [PDF]

Physical Review D, 2013
In this paper we discuss a new way to derive neutrino mixing patterns, which originates from the idea proposed in a recent article by Hernandez and Smirnov. Its applications to various cases are discussed. We first present the complete set of possible mixing patterns for the minimal case where unbroken residual symmetries of the Majorana neutrino and ...

Leptogenesis in an SU(5)×A5 golden ratio flavour model

Nuclear Physics B, 2015
In this paper we discuss a minor modification of a previous SU(5)×A5 flavour model which exhibits at leading order golden ratio mixing and sum rules for the heavy and the light neutrino masses.

THEORY OF NEUTRINO MASSES AND MIXINGS [PDF]

International Journal of Modern Physics A, 2002
Neutrino physics is going through a revolutionary progress. In this talk I review what we have learned and why neutrino mass is so important. Neutrino masses and mixings are already shedding new insight into the origin of flavor. Given the evidences for neutrino mass, leptogenesis is gaining momentum as the origin of cosmic baryon asymmetry.

θ23 Octant sensitivity in presence of light sterile and active ν and ν¯ oscillations using beamline experiments

Nuclear Physics B
We examine the octant sensitivity of the long-baseline neutrino oscillation experiments in view of light sterile neutrino flavors with masses in the 1 eV range. Considering the active-sterile mixing, we explore the possible preferred running modes either

Theory of neutrino slow flavor evolution. Part II. Space-time evolution of linear instabilities

Journal of High Energy Physics
Slow flavor evolution (defined as driven by neutrino masses and not necessarily “slow”) is receiving fresh attention in the context of compact astrophysical environments.

Terrestrial matter effects on reactor antineutrino oscillations: constant vs. fluctuated density profiles

Journal of High Energy Physics
The JUNO Collaboration has recently released its first reactor antineutrino oscillation result, achieving unprecedented precision in the measurement of ∆ m 21 2 $$ \Delta {m}_{21}^2 $$ and sin2 θ 12.

Theory of neutrino slow flavor evolution. Part I. Homogeneous medium

Journal of High Energy Physics
Dense neutrino gases can exhibit collective flavor instabilities, triggering large flavor conversions that are driven primarily by neutrino-neutrino refraction.
