El neutrino es una partícula elemental neutra que fue propuesta por Pauli en el año 1930 para explicar la aparente violación de la conservación de la energía y momento en desintegraciones beta. La débil interacción de esta partícula con la ma

The solar neutrino flux arrives at Earth as an incoherent admixture of mass eigenstates, and then solar neutrino detection constitute a blind probe to the oscillation pattern of the neutrino flavour conversion. Consequently, it is also impossible to

Neutrino decay and solar neutrino seasonal effect

Autor: Picoreti Nakahara, Renan, 1986, Guzzo, Marcelo Moraes, 1963, Holanda, Pedro Cunha de, 1973, Peres, Orlando Luis Goulart, 1969

We consider the possibility of solar neutrino decay as a sub-leading effect on their propagation between production and detection. Using current oscillation data, we set a new lower bound to the nu(2) neutrino lifetime at tau(2)/m(2) >= 7.2 x 10(-4)
