Method for Determination of |Ue3| in Neutrino Oscillation Appearance Experiments
نویسندگان
چکیده
We point out that determination of the MNS matrix element |Ue3| = s13 in long-baseline νμ → νe neutrino oscillation experiments suffers from large intrinsic uncertainty due to the unknown CP violating phase δ and sign of ∆m213. We propose a new strategy for accurate determination of θ13; tune the beam energy at the oscillation maximum and do the measurement both in neutrino and antineutrino channels. We show that it automatically resolves the problem of parameter ambiguities which involves δ, θ13, and the sign of ∆m213.

A MONOCHROMATIC NEUTRINO BEAM FOR θ13 and δ a
The goal for future neutrino facilities is the determination of the [Ue3] mixing and CP violation in neutrino oscillations. This will require precision experiments with a very intense neutrino source. Here a novel method to create a monochromatic neutrino beam based on the recent discovery of nuclei that decay fast through electron capture is discussed. The boost of such radioactive ions will g...
متن کاملPossibility of the Lbl Experiment with the High Intensity Proton Accelerator ⋆
We study physics possibility of Very Long Base-Line (VLBL) Neutrino-Oscillation Experiments with the High Intensity Proton Accelerator, which will be completed by the year 2007 in Tokai-village, Japan. As a target, a 100 kton-level water-Čerenkov detector is considered at 2,100 km away. Assuming the pulsed narrow-band νμ beams, we study sensitivity of such experiments to the neutrino mass hiera...
متن کاملImplications of CHOOZ results for the decoupling of solar and atmospheric neutrino oscillations
We have considered the results of solar and atmospheric neutrino oscillation experiments in the scheme of mixing of three neutrinos with a mass hierarchy. It is shown that the recent results of the CHOOZ experiment imply that |Ue3| ≪ 1 (U is the neutrino mixing matrix), that the oscillations of solar neutrinos are described by the two-generation formalism and that the oscillations of solar and ...
متن کاملAtmospheric Neutrino Oscillations among Three Neutrino Flavors and Long-baseline Experiments
Anticipating future long-baseline neutrino experiments to search for neutrino oscillations in various oscillation channels, we have analyzed the atmospheric neutrino data in the framework of a model with mixing of three massive neutrino fields that can accommodate the data of solar neutrino experiments. The oscillations of atmospheric and terrestrial neutrinos are described in this model by thr...
متن کاملhep-ph/0007029 Reply to “Is Ue3 really related to the solar neutrino solutions?”
In a recent paper [1] we showed that, assuming no fine tuning between certain elements of the neutrino mass matrix, one can link the element Ue3 of the lepton mixing matrix to solar and atmospheric neutrino oscillation parameters. This result has been recently criticized by Haba and Suzuki [2]. In the present note we show that their criticism is not valid and just reflects their failure to unde...
