Atmospheric neutrinos in ice and measurement of neutrino oscillation parameters
A large number of experiments of different types have provided strong evidence for neutrino oscillations and thus for physics beyond the Standard Model (see Ref. [1] and references therein). Cosmic ray interactions in the atmosphere give a natural source of neutrinos. These atmospheric neutrinos in the GeV range have been used by the Super-Kamiokande (SK) detector to provide evidence for neutri...
متن کاملAtmospheric Neutrino Tests of Neutrino Oscillation Mechanisms
Recent Super-Kamiokande data on the atmospheric neutrino anomaly are used to test various mechanisms for neutrino oscillations. It is found that the current atmospheric neutrino data alone cannot rule out any particular mechanism. Future long-baseline experiments should play an important role in identifying the underlying neutrino oscillation mechanism.
متن کاملConstraining neutrino oscillation parameters with current solar and atmospheric data
We analyse the impact of recent solar and atmospheric data in the determination of the neutrino oscillation parameters, taking into account that both the solar νe and the atmospheric νμ may convert to a mixture of active and sterile neutrinos. In addition to the recent SNO neutral current (NC), spectral and day/night data we add the latest 1496day solar and 1489-day atmospheric Super-K neutrino...
متن کاملUnraveling neutrino parameters with a magical beta-beam experiment at INO
We expound in detail the physics reach of an experimental set-up in which the proposed large magnetized iron detector at the India-based Neutrino Observatory (INO) would serve as the far detector for a so-called beta-beam. If this pure νe and/or ν̄e beam is shot from some source location like CERN such that the source-detector distance L ≃ 7500 km, the impact of the CP phase δCP on the oscillati...
متن کاملFour neutrino oscillation analysis of the Superkamiokande atmospheric neutrino data
Superkamiokande atmospheric neutrino data (contained and upward going through μ events) for 990 days are analyzed in the framework of four neutrinos (three active and one sterile neutrinos) without imposing constraints of Big Bang Nucleosynthesis. It is shown that the wide range of the oscillation parameters is allowed at 90% confidence level (0.1 ∼ |Us1| + |Us2| ≤ 1), where the best fit point ...
