Hadron Production Experiments

, 2017
Precise prediction of the neutrino flux is a key ingredient to achieving the physics goals of accelerator-based neutrino experiments. In modern accelerator-based neutrino experiments, neutrino beams are created by colliding protons with a nuclear target.

Atmospheric neutrinos and discovery of neutrino oscillations

Proceedings of the Japan Academy, Series B, 2010
Neutrino oscillation was discovered through studies of neutrinos produced by cosmic-ray interactions in the atmosphere. These neutrinos are called atmospheric neutrinos. They are produced as decay products in hadronic showers resulting from collisions of cosmic rays with nuclei in the atmosphere.

The physics case for neutrino–neutrino collisions

Journal of Physics G: Nuclear and Particle Physics
Abstract Addressing the mass origin and properties of neutrinos is of strong interest to particle physics, baryogenesis and cosmology. Popular explanations involve physics beyond the standard model, for example, the dimension-5 Weinberg operator or heavy Majorana neutrinos arising from ‘seesaw’ models.

Neutrinos from the Early Universe and physics beyond standard models

Open Physics, 2015
Neutrino oscillations present the only robust example of experimentally detected physics beyond the standard model. This review discusses the established and several hypothetical beyond standard models neutrino characteristics and their cosmological ...

Compreendendo a oscilação dos neutrinos

Revista Brasileira de Ensino de Física
Este trabalho é uma introdução ao modelo da oscilação de neutrinos para estudantes de física. Apresentamos o modelo de mistura de neutrinos baseado no conceito de superposição de estados. Em particular, consideraremos o caso onde os neutrinos se propagam

The decays "neutrino{heavy} -> neutrino{light} + photon" and "neutrino{heavy} -> neutrino{light} e+ e-" of massive neutrinos

, 1999
If, as recently reported by the Super-Kamiokande collaboration, the neutrinos are massive, the heaviest one would not be stable and, though chargeless, could in particular decay into a lighter neutrino and a photon by quantum loop effects. The corresponding rate is computed in the standard model with massive Dirac neutrinos as a function of the ...

Ultrahigh energy neutrinos with a mediterranean neutrino telescope

, 2007
A study of the ultra high energy neutrino detection performances of a km^3 Neutrino Telescope sitting at the three proposed sites for "ANTARES", "NEMO" and "NESTOR" in the Mediterranean sea is here performed.
