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.

Solar neutrino detection sensitivity in DARWIN via electron scattering

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We detail the sensitivity of the proposed liquid xenon DARWIN observatory to solar neutrinos via elastic electron scattering. We find that DARWIN will have the potential to measure the fluxes of five solar neutrino components: pp, $$^7$$ 7 Be, $$^{13 ...

Muon and Tau Neutrinos Spectra from Solar Flares

open access: yes, 2003
Solar neutrino flares and mixing are considered. Most power-full solar flare as the ones occurred on 23th February 1956, September 29th 1989, 28th October and on 2nd-4th November 2003 are sources of cosmic rays, X, gamma and neutrino bursts. These flares

Solar Neutrino Measurements

open access: yes, 2018
We present the most recent results from the two currently running solar neutrino experiments, Borexino at the Gran Sasso laboratory in Italy and SuperK at Kamioka mine in Japan. SuperK has released the most precise yet measurement of the 8B solar neutrino interaction rate, with a precision better than 2\%, consistent with a constant solar neutrino ...

The Solar Neutrino Problem [PDF]

open access: yesAnnual Review of Astronomy and Astrophysics, 1995
The solar neutrino problem has persisted for almost three decades. Recent results from Kamiokande, SAGE, and GALLEX indicate a pattern of neutrino fluxes that is very difficult to reconcile with plausible variations in standard solar models. This situation is reviewed, and suggested particle physics solutions are discussed.

Intermediate Fluence Downward Terrestrial Gamma Ray Flashes as Observed by the Telescope Array Surface Detector

open access: yesJournal 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

Solar neutrinos and the strongest oscillation constraints on scalar NSI

open access: yesJournal of High Energy Physics
Scalar non-standard neutrino interactions (sNSI) is a scenario where neutrinos can develop a medium dependent contribution to their mass due to a new scalar mediator.

Recent Borexino results and prospects for the near future

open access: yesEPJ Web of Conferences, 2016
The Borexino experiment located in the Gran Sasso National Laboratory, is an organic liquid scintillator detector conceived for the real time spectroscopy of low energy solar neutrinos.

Constraints on neutrino oscillation parameters from the measurement of day-night solar neutrino fluxes at Super-Kamiokande [PDF]

open access: yes, 1998
A search for day-night variations in the solar neutrino flux resulting from neutrino oscillations has been carried out using the 504 day sample of solar neutrino data obtained at Super-Kamiokande.

The evolution and history of Vinca alkaloids: From the Big Bang to the treatment of pediatric acute leukemia

open access: yesPediatric Blood &Cancer, Volume 71, Issue 11, November 2024.
Abstract An attractive flower from the island of Madagascar has in part saved the lives of thousands of children with acute lymphoblastic leukemia (ALL). Random mutations and alterations to the genome led to the evolution of genes encoding enzymes, which would provide the periwinkle flower an arsenal of secondary metabolites to survive within the ...
