Neutrino energy-loss rate in 331β model

Radiative corrections to neutrino energy loss rate in stellar interiors

We consider radiative electromagnetic corrections, at order α, to the process e+e− → νν at finite density and temperature. This process represents one of the main contributions to the cooling of stellar environments in the late stages of star evolution. We find that these corrections affect the energy loss rate by a factor which can be as large as −20% with respect to the tree level estimate, i...

Dark Energy and Neutrino Model in SUSY

We discuss the effect of the supersymmetry breaking on the Mass Varying Neutrinos(MaVaNs) scenario. Especially, the effect mediated by the gravitational interaction between the hidden sector and the dark energy sector is studied. A model including a chiral superfield in the dark sector and the right-handed neutrino superfield is proposed. Evolutions of the neutrino mass and the equation of stat...

an appropriate model for exchange rate predictability in iran: comparing potential forecastability

nowadays in trade and economic issues, prediction is proposed as the most important branch of science. existence of effective variables, caused various sectors of the economic and business executives to prefer having mechanisms which can be used in their decisions. in recent years, several advances have led to various challenges in the science of forecasting. economical managers in various fi...

High Rate Neutrino Detectors for Neutrino Factories

Three types of high rate neutrino detectors for neutrino interaction physics at neutrino factories are discussed. High performance general-purpose detectors might collect event samples on the order of a billion events or more. This could greatly improve on existing analyses of neutrino interactions and also lead to new and important analysis topics including, for example, precise determinations...
