The Super-Kamiokande experiment

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
Super-Kamiokande is a gigantic and versatile detector able to detect neutrinos with energies between a few MeV and a few hundred GeV. Super-K started data taking on 1st of April in 1996 after 5 years construction period and obtained compelling evidence ...

Vacuum Neutrino Oscillations of Solar Neutrinos and Lepton Mass Matrices [PDF]

open access: yes, 1998
We consider the case that the solar neutrino deficit is due to the vacuum oscillation. The lepton mass matrices with nearly bi-maximal mixings are needed in order to explain both solar and atmospheric neutrino deficit.

Implications of CHOOZ results for the decoupling of solar and atmospheric neutrino oscillations

open access: yes, 1998
We have considered the results of solar and atmospheric neutrino oscillation experiments in the scheme of mixing of three neutrinos with a mass hierarchy.

Phenomenology of Pseudo Dirac Neutrinos [PDF]

open access: yes, 2000
We formulate general conditions on $3\times 3$ neutrino mass matrices under which a degenerate pair of neutrinos at a high scale would split at low scale by radiative corrections involving only the standard model fields.

Sensitivity to neutrino-antineutrino transitions for boron neutrinos

open access: yesNuclear Physics B, 2019
Neutrino-antineutrino conversion is an important new physics process. The observation of this phenomenon could indicate total lepton number violation and potential CPT-violation. Searching for the appearance of electron antineutrinos from solar neutrinos

Searches for atmospheric long-lived particles

open access: yesJournal of High Energy Physics, 2020
Long-lived particles are predicted in extensions of the Standard Model that involve relatively light but very weakly interacting sectors. In this paper we consider the possibility that some of these particles are produced in atmospheric cosmic ray ...

New oscillation and scattering constraints on the tau row matrix elements without assuming unitarity

open access: yesJournal of High Energy Physics, 2022
The tau neutrino is the least well measured particle in the Standard Model. Most notably, the tau neutrino row of the lepton mixing matrix is quite poorly constrained when unitarity is not assumed.

Democratic approach to atmospheric and solar neutrino oscillations

open access: yesPhysics Letters B, 2002
Working with a ${\cal U}(1)$ flavor symmetry, we show how the hierarchical structure in the charged fermion sector and a democratic approach for neutrinos that yields large solar and atmospheric neutrino mixings can be simultaneously realized in the MSSM framework. However, in SU(5) due to the unified multiplets we encounter difficulties.

Highlights from Super-Kamiokande

open access: yesEPJ Web of Conferences, 2016
Recent results from Super-Kamiokande experiment are reviewed in this paper; Neutrino mass hierarchy and CP violation in the lepton sector are investigated via νμ → νe oscillation of the atmospheric neutrinos.

Impact of form factor uncertainties on interpretations of coherent elastic neutrino-nucleus scattering data

open access: yesJournal of High Energy Physics, 2019
The standard model coherent elastic neutrino-nucleus scattering (CEνNS) cross section is subject to nuclear form factor uncertainties, mainly driven by the root-mean-square radius of the neutron density distribution.
