Modeling the Lunar Radiation Environment: A Comparison Among FLUKA, Geant4, HETC‐HEDS, MCNP6, and PHITS

open access: yesSpace Weather, Volume 20, Issue 8, August 2022., 2022
Abstract Radiation transport codes have been an increasingly important tool for studying the space radiation environment, which includes high‐energy and high‐nuclear‐charge particles. The unique advantage of transport models lies in covering a wider range of particles, energies, and angles than would be attainable in a laboratory or measurable by an ...

Non-Zero Electric Charge of the Neutrino and the Solar Neutrino Problem [PDF]

open access: yes, 1994
It has recently been shown that the neutrino can have non-zero electric charge in a number of gauge theories, including the Minimal Standard Model. Assuming non-zero neutrino charge, we develop a new approach to the solar neutrino problem.

Confronting spin flavor solutions of the solar neutrino problem with current and future solar neutrino data [PDF]

open access: yes, 2002
A global analysis of spin flavor precession (SFP) solutions to the solar neutrino problem is given, taking into account the impact of the full set of latest solar neutrino data, including the recent SNO data and the 1496-day Super-Kamiokande data.

Expanding Nuclear Physics Horizons with the Gamma Factory

open access: yesAnnalen der Physik, Volume 534, Issue 3, March 2022., 2022
The Gamma Factory is an ambitious proposal for a source of photons with energies up to hundreds of MeV and photon fluxes exceeding those of the currently available gamma sources by orders of magnitude. The paper surveys the new opportunities in nuclear physics and related fields that may be afforded by the this facility. Abstract The Gamma Factory (GF)

The Simplest Resonant Spin--Flavour Solution to the Solar Neutrino Problem [PDF]

open access: yes, 2000
We re-analyse the resonant spin-flavour (RSF) solutions to the solar neutrino problem in the framework of analytic solutions to the solar magneto-hydrodynamics (MHD) equations.

Global analysis with SNO: Toward the solution of the solar neutrino problem [PDF]

open access: yes, 2001
We perform a global analysis of the latest solar neutrino data including the SNO result on the CC-event rate. This result further favors the LMA solution of the solar neutrino problem.

The Status of the Solar Neutrino Problem [PDF]

open access: yesAnnual Review of Nuclear and Particle Science, 1993
Perhaps the most outstanding discrepancy between prediction and measurements in current particle physics comes from the solar neutrino problem, in which a large deficit of high-energy solar neutrinos is observed. Many Nonstandard Solar Models have been invoked to try to reduce the predicted flux, but all have run into problems in trying to reproduce ...

Status of the solution to the solar neutrino problem based on nonstandard neutrino interactions [PDF]

open access: yes, 2000
We analyze the current status of the solution to the solar neutrino problem based both on (a) nonstandard flavor-changing neutrino interactions (FCNI) and (b) nonuniversal flavor diagonal neutrino interactions (FDNI).

The Nature of Massive Neutrinos

open access: yesAdvances in High Energy Physics, 2013
The compelling experimental evidences for oscillations of solar, reactor, atmospheric, and accelerator neutrinos imply the existence of 3-neutrino mixing in the weak charged lepton current.

Sensitivity of a low threshold directional detector to CNO-cycle solar neutrinos

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
A first measurement of neutrinos from the CNO fusion cycle in the Sun would allow a resolution to the current solar metallicity problem. Detection of these low-energy neutrinos requires a low-threshold detector, while discrimination from radioactive ...
