Self Consistent Modeling of Relativistic Runaway Electron Beams Giving Rise to Terrestrial Gamma‐Rays Flashes

open access: yesJournal of Geophysical Research: Space Physics, Volume 129, Issue 5, May 2024.
Abstract Terrestrial Gamma Ray Flashes (TGFs) are short bursts of gamma rays occurring during thunderstorms. They are believed to be produced by Relativistic Runaway Electron Avalanches (RREAs). In this paper, we present a new numerical model based on the Particle‐In‐Cell (PIC) method to simulate the interactions between the electromagnetic fields and ...

Relating the small parameters of neutrino oscillations

open access: yesPhysics Letters B, 2015
Neutrino oscillations reveal several small parameters, namely, θ13, the solar mass splitting vis-à-vis the atmospheric one, and the deviation of θ23 from maximal mixing.

Challenge to anomalous phenomena in solar neutrino

open access: yesJournal of High Energy Physics, 2021
We suggest a would-be solution to the solar neutrino tension why solar neutrinos appear to mix differently from reactor antineutrinos, in theoretical respect.

Effects of Forbush Decreases on the Global Electric Circuit

open access: yesSpace Weather, Volume 22, Issue 4, April 2024.
Abstract The suppression of high‐energy cosmic rays, known as Forbush decreases (FDs), represents a promising factor in influencing the global electric circuit (GEC) system. Researchers have delved into these effects by examining variations, often disruptive, of the potential gradient (PG) in ground‐based measurements taken in fair weather regions.

Status of global fits to neutrino oscillations [PDF]

open access: yes, 2004
We review the present status of global analyses of neutrino oscillations, taking into account the most recent neutrino data including the latest KamLAND and K2K updates presented at Neutrino2004, as well as state-of-the-art solar and atmospheric neutrino

Solar neutrino experiments and neutrino oscillations [PDF]

open access: yesAIP Conference Proceedings, 1981
This report will give the results of the Brookhaven solar neutrino experiment that is based upon the neutrino capture reaction, /sup 37/Cl (..nu..,e/sup -/)/sup 37/Ar. The experiment was built in 1967 to test the theory of solar energy production, and it is well known that the neutrino capture rate in the detector is lower than that expected from ...

Heavy Elements and Electromagnetic Transients from Neutron Star Mergers

open access: yesAnnalen der Physik, Volume 536, Issue 2, February 2024.
Astro‐(physics) has made major leaps forward through the combined information provided by both gravitational waves and electromagnetic emission from the first detected neutron star merger event. This review provides an up‐to‐date overview of today's understanding of neutron star mergers and their electromagnetic emission and it discusses possible ...

Measurement of the νe and total 8B solar neutrino fluxes with the Sudbury Neutrino Observatory phase-III data set [PDF]

open access: yes, 2011
This paper details the solar neutrino analysis of the 385.17-day phase-III data set acquired by the Sudbury Neutrino Observatory (SNO). An array of He-3 proportional counters was installed in the heavy-water target to measure precisely the rate of ...

Nuclear astrophysicists at war

open access: yesNatural Sciences, Volume 4, Issue 1, January 2024.
The Manhattan program not only opened the path to the nuclear age for humans, but also triggered a lot of new questions and research directions in nuclear physics and astrophysics that still inform the ideas in these fields today. Abstract The question of energy production in stars stimulated an entire generation of young physicists in the 1930s who ...

Measurement of the 8B solar neutrino flux with the KamLAND liquid scintillator detector [PDF]

open access: yes, 2011
We report a measurement of the neutrino-electron elastic scattering rate from ^8B solar neutrinos based on a 123 kton-day exposure of KamLAND. The background-subtracted electron recoil rate, above a 5.5-MeV analysis threshold is 1.49 ± 0.14(stat) ± 0.17 ...
