Future neutrino physics with Hyper-Kamiokande [PDF]
EPJ Web of ConferencesHyper-Kamiokande, the next-generation neutrino observatory in Japan, evolves from its predecessors, Kamiokande, Super-Kamiokande and T2K, with a significant upgrade to a 258-kton water Cherenkov detector equipped with 20,000 PMTs.

Searching for neutrino oscillation parameters in long baseline experiments [PDF]
arXiv, 2016 Developing neutrino astronomy requires a good understanding of the neutrino oscillations mechanism. The European strategy for neutrino oscillation physics sets a high priority on future long baseline neutrino experiments with the aim to measure the intrinsic parameters that govern the neutrino oscillations.

Neutrino oscillations: from an historical perspective to the present status [PDF]
, 2016 The history of neutrino mixing and oscillations is briefly presented. Basics of neutrino mixing and oscillations and convenient formalism of neutrino oscillations in vacuum is given. The role of neutrino in the Standard Model and the Weinberg mechanism of the generation of the Majorana neutrino masses are discussed.

Journal of Geophysical Research: Atmospheres, Volume 129, Issue 24, 28 December 2024.Abstract On 11 September 2021, two small thunderstorms developed over the Telescope Array Surface Detector (TASD) that produced an unprecedented number of six downward terrestrial gamma ray flashes (TGFs) within one‐hour timeframe. The TGFs occurred during the initial stage of negative cloud‐to‐ground flashes whose return strokes had increasingly large

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 ...

An unorthodox alternative for righthanded neutrinos: lefthanded see-saw [PDF]
Acta Phys.Polon. B31 (2000) 673-679, 1999 A new lefthanded see-saw mechanism is constructed, implying both the smallness of active-neutrino masses and decoupling of heavy passive neutrinos, similarly to the situation in the case of conventional see-saw. But now, in place of the conventional righthanded neutrinos, the lefthanded sterile neutrinos play the role of heavy passive neutrinos, the ...

Neutrino oscillations in cosmological spacetime
Nuclear Physics B, 2021 Neutrino physics is one of the most intriguing and vividly discussed topics in high-energy physics. Phenomena of neutrino oscillation give rise to a large number of experiments to actually observe these oscillations among different flavors of neutrinos ...

Neutrino-neutrino and neutrino-matter helicity flip interactions [PDF]
arXiv, 2001 Taking into account that neutrinos are massive particles and that they are produced mainly as states of negative helicity, we show that the neutral and charged current interactions change these neutrinos into transversally polarized states. This implies a considerable reduction of the neutrino flux when propagating through ordinary matter (electrons ...

Extra Long Baseline Neutrino Oscillations and CP Violation [PDF]
arXiv, 2001 The potential for studying CP violation in neutrino oscillations using conventional neutrino and anti-neutrino beams is examined.
