Matter profile effect in neutrino factory

نویسنده

چکیده

We point out that the matter profile effect — the effect of matter density fluctuation on the baseline — is very important to estimate the parameters in a neutrino factory with a very long baseline. To make it clear, we propose the method of the Fourier series expansion of the matter profile. By using this method, we can take account of both the matter profile effect and its ambiguity. For very long baseline experiment, such as L = 7332km, in the analysis of the oscillation phenomena we need to introduce a new parameter a1— the Fourier coefficient of the matter profile — as a theoretical parameter to deal with the matter profile effects.

Non-standard Interactions: Atmospheric versus Neutrino Factory Experiments

We consider the potential of a generic neutrino factory (NUFACT) in probing non– standard neutrino–matter interactions (NSI). We find that the sensitivity to flavourchanging (FC) NSI can be substantially improved with respect to present atmospheric neutrino data, especially at energies higher than approximately 50 GeV, where the effect of the tau mass is small. For example, a 100 GeV NUFACT can...

Fe b 20 07 Physics with a very long neutrino factory baseline Raj Gandhi

We discuss the neutrino oscillation physics of a very long neutrino factory baseline over a broad range of lengths (between 6 000 km and 9 000 km), centered on the “magic baseline” (∼ 7 500 km) where correlations with the leptonic CP phase are suppressed by matter effects. Since the magic baseline depends only on the density, we study the impact of matter density profile effects and density unc...
