Improved precision on 2–3 oscillation parameters using the synergy between DUNE and T2HK

Journal of High Energy Physics
A high-precision measurement of ∆ m 31 2 $$ \Delta {m}_{31}^2 $$ and θ 23 is inevitable to estimate the Earth’s matter effect in long-baseline experiments which in turn plays an important role in addressing the issue of neutrino mass ordering and to ...

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 ...

Limits on sterile neutrino mixing using atmospheric neutrinos in Super-Kamiokande [PDF]

, 2014
We present limits on sterile neutrino mixing using 4,438 live-days of atmospheric neutrino data from the Super-Kamiokande experiment. We search for fast oscillations driven by an eV$^2$-scale mass splitting and for oscillations into sterile neutrinos ...

Multi‐Photon 3D Laser Micro‐Printed Plastic Scintillators for Applications in Low‐Energy Particle Physics

Advanced Functional Materials, Volume 35, Issue 2, January 9, 2025.
Many modern detector systems require structured scintillators in combination with photo‐detectors. This requirement can be fulfilled by 3D printing plastic scintillators which becomes more and more relevant. However, the resolution and surface quality of 1‐photon‐based 3D printing techniques are not sufficient for many applications.

Large solar neutrino mixing and radiative neutrino mechanism

Physics Letters B, 2002
We find that the presence of a global $L_e-L_ -L_ $ ($\equiv L^\prime$) symmetry and an $S_2$ permutation symmetry for the $ $- and $ $-families supplemented by a discrete $Z_4$ symmetry naturally leads to almost maximal atmospheric neutrino mixing and large solar neutrino mixing, which arise, respectively, from type II seesaw mechanism initiated ...

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

Journal 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

Flavor in SU(5)$SU(5)$ Finite Grand Unified Models

Fortschritte der Physik, Volume 72, Issue 12, December 2024.
Abstract Four SU(5)N=1$SU(5) \nobreakspace N=1$ supersymmetric models which exhibit S3$S_3$ and/or ZN$Z_N$ symmetries are studied, that are finite to two or all loops, and their corresponding mass matrices. The first is an all‐loop finite model based on an S3×Z3×Z2$S_3\times Z_3\times Z_2$ flavor symmetry, which leads to phenomenologically nonviable ...

Δ(27) family symmetry and neutrino mixing

, 2015
The observed neutrino mixing, having a near maximal atmospheric neutrino mixing angle and a large solar mixing angle, is close to tri-bi-maximal. This structure may be related to the existence of a discrete non-Abelian family symmetry.

Reproducing lepton mixing in a texture zero model

, 2013
We note that the emerging features of lepton mixing can be reproduced if, with inverted neutrino mass ordering, both the smallest neutrino mass and the $\tau\tau$ element of the neutrino mass matrix vanish.
