Constraining non standard neutrino interactions
Non-standard interactions (NSI) arise naturally when considering physics beyond the Standard Model. In particular, they can have an important influence in the solar neutrino analysis. The current status of NSI constraints will be discussed and the perspectives of future neutrino experiments will be briefly outlined.
متن کاملConstraining Galactic Neutrino Production in pγ Interactions with Cosmic Ray Electron and Positron Spectra
High energy neutrinos are expected to be produced inside astrophysical sources of cosmic rays e.g. supernova remnants, pulsar wind nebulae, active galactic nuclei and gamma-ray bursts by the decay of charged pions produced in pγ and pp interactions. Although pp interactions may be the dominant mechanism in our Galaxy, it is unclear how important pγ process is for neutrino production. We show th...
متن کاملNonstandard 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...
متن کاملConstraining neutrino magnetic moment with solar and reactor neutrino data
We use solar neutrino data to derive stringent bounds on Majorana neutrino transition moments (TMs). Such moments, if present, would contribute to the neutrino– electron scattering cross section and hence alter the signal observed in Super-Kamiokande. Using the latest solar neutrino data, combined with the results of the reactor experiment KamLAND, we perform a simultaneous fit of the oscillati...
متن کاملEffects of non-standard neutrino-electron interactions on relic neutrino decoupling
We consider the decoupling of neutrinos in the early Universe in presence of nonstandard neutral current neutrino-electron interactions (NSI). We first discuss a semi-analytical approach to solve the relevant kinetic equations and then present the results of fully numerical and momentum-dependent calculations, including flavor neutrino oscillations. We present our results in terms of both the e...
