چکیده

Processes with precisely known cross sections, like neutrino electron elastic scattering ($\nu e^{-} \!\rightarrow \nu e^{-}$) and inverse muon decay ($\nu_\mu \mu^{-} \nu_e$) have been used by MINERvA to constrain the uncertainty on NuMI beam flux. This work presents a new measurement of electrons using medium energy \numubar enhanced beam. A sample 578 events after background subtraction is in combination previous \numu reduce flux \numu-enhanced from 7.6\% 3.3\% \numubar-enhanced 7.8\% 4.7\%.

Effects of neutrino mixing on high-energy cosmic neutrino flux

Several cosmologically distant astrophysical sources may produce high-energy cosmic neutrinos (E ≥ 10 GeV) of all flavors above the atmospheric neutrino background. We study the effects of vacuum neutrino mixing in three flavor framework on this cosmic neutrino flux. We also consider the effects of possible mixing between the three active neutrinos and the (fourth) sterile neutrino with or with...

Nonstandard neutrino properties and the high-energy cosmic neutrino flux

Recently, it has been shown that cosmic neutrino flux at the GRB/AGN source, F 0 νe : F 0 νμ : F 0 ντ ≃ 1 : 2 : 0 , inevitably oscillates (in the three neutrino framework) to 1 : 1: 1, irrespective of the mixing angle relevant to the solar data. It has also been pointed out that the intrinsic flux of the cosmic highenergy neutrinos may not have the standard ratio, in which case the cosmic neutr...

Neutrino oscillations in high energy cosmic neutrino flux

I discuss the effects of neutrino oscillations on high energy cosmic neutrinos which come from cosmologically distant astrophysical sources. I incorporate all the up-to-date constraints from the solar, atmospheric, reactor, accelerator data and give the possible pattern for the ratio of the high energy cosmic neutrinos in the cases of three and four neutrino schemes.

Neutrino energy quantization in rotating medium

Exact solution of the modified Dirac equation in rotating medium is found in polar coordinates in the limit of vanishing neutrino mass. The solution for the active lefthanded particle exhibit properties similar to those peculiar for the charged particle moving in the presence of a constant magnetic field. Accordingly, the particle in the rotating matter has circle orbits with energy levels, ana...

Reviving the energy independent suppression of the solar neutrino flux

We explore the possibility of an energy independent suppression of the solar neutrino flux in the context of the recent SuperKamiokande data. From a global analysis of the rate and spectrum data, this scenario is allowed at only 14% probability with the observed Cl rate. If we allow for a 20% upward renormalisation of the Cl rate along with a downward renormalisation of the B neutrino flux then...
