The sign of ∆m31 and the muon-charge asymmetry for atmospheric neutrinos
نویسنده
چکیده
We discuss the possibility to measure the sign of ∆m31 from matter-induced charge asymmetries in atmospheric neutrino oscillations. The main conclusion is that an impact on the νμ survival probability requires the action of the MSW resonance, which becomes visible for baselines above ∼ 7000 km. ∗Talk given at the 7th International Workshop on Topics in Astroparticles and Underground Physics (TAUP2001), Laboratori Nazionali del Gran Sasso, Italy, September 8-12, 2001.

Observable Medium Effects For Atmospheric Neutrinos
We discuss the possibility to observe matter effects in atmospheric neutrino oscillations. The main conclusion is that an impact on the νμ survival probability requires the action of the MSW resonance, which becomes visible for baselines above ∼ 7000 km. The associated muon charge asymmetry carries information on θ13 and the sign of ∆m31. ∗Talk given at the EPS-Conference on HEPP, Budapest (Hun...
متن کاملGetting the Most from Atmospheric Neutrinos
Observations of atmospheric neutrinos by the SuperKamiokande collaboration have demonstrated large mixing of the muon-neutrino. However the present atmospheric neutrino data does not significantly constrain the associated mixing of the electron-neutrino, or the sign of the mass-squared difference. Here we identify the diagnostics for these quantities and they also test the theory of how matter ...
متن کاملThree-Neutrino Oscillations of Atmospheric Neutrinos, θ13, Neutrino Mass Hierarchy and Iron Magnetized Detectors
We derive predictions for the Nadir angle (θn) dependence of the ratio Nμ−/Nμ+ of the rates of the μ− and μ+ multi-GeV events, and for the μ−−μ+ event rate asymmetry, Aμ−μ+ = [N(μ −)−N(μ+)]/[N(μ−)+N(μ+)], in iron-magnetized calorimeter detectors (MINOS, INO, etc.) in the case of 3-neutrino oscillations of the atmospheric νμ and ν̄μ, driven by one neutrino mass squared difference, |∆m31| ∼ (2.0−3...
متن کاملCharge ratio of muons from atmospheric neutrinos
We calculate the intensities and angular distributions of positive and negative muons produced by atmospheric neutrinos. We comment on some sources of uncertainty in the charge ratio. We also draw attention to a potentially interesting signature of neutrino oscillations in the muon charge ratio, and we discuss the prospects for its observation (which are not quite within the reach of currently ...
متن کاملAtmospheric Neutrinos as a Probe of CPT Violation
We show that atmospheric neutrinos can provide a sensitive and robust probe of CPT violation (CPTV). We perform realistic event-rate calculations and study the variations of the ratio of total muon to antimuon survival rates with L/E and L (L ≡ baseline length, E ≡ neutrino energy) in a detector capable of identifying the muon charge. We demonstrate that measurements of these ratios when couple...
