چکیده

We have predicted CP violation in the long baseline accelerator experiments taking into consideration the recent LSND data and the atmospheric neutrino data. By using both data, we can get unambiguous results for CP violation. Those data prefer the mass hierarchy m3 ≃ m2 ≫ m1 with m3 = O(1eV) and the flavor mixings |Ue1| ≃ 1 and |Uμ1| ≪ 1. The estimated upper bound of CP violation is 0.006, which may be observable in the long baseline accelerator experiments. The matter effect, which is not CP invariant, is found to be very small.

Long-baseline neutrino oscillation experiments and CP violation in the lepton sector

We discuss possibilities to investigate the effects of CP (and T) violation in the lepton sector in neutrino oscillation experiments. We consider the effects of CP violation in the framework of two schemes of mixing of four massive neutrinos that can accommodate the results of all neutrino oscillation experiments. Using the constraints on the mixing parameters that follow from the results of sh...

Recent Results and Future Prospects of Neutrino Oscillation Experiments

Since the discovery of non-zero θ13 and oscillation-induced electron neutrino appearance, it has become possible to address the question of CP violation in neutrino oscillations in long-baseline experiments. Though current experiments have already begun to constrain δcp, the parameter responsible for CP violation in the PMNS mixing paradigm, uncertainties in other oscillation parameters remain ...

CP violation and matter effect in long-baseline neutrino oscillation in the four-neutrino model

We investigate the CP violation effect and the matter effect in the long-baseline neutrino oscillations in the four-neutrino model with mass scheme of the two pairs of two close masses separated by a gap of the order of 1 eV by using the constraints on the mixing matrix derived from the solar neutrino deficit, atmospheric neutrino anomaly, LSND experiments, and the other terrestrial neutrino os...

CP - and T -Violation Effects in Long Baseline Neutrino Oscillation Experiments

We examine how large CP and T -violation effects are allowed in long baseline neutrino experiments with three generations of neutrinos, considering both the solar neutrino deficit and the atmospheric neutrino anomaly. We considerd two cases: When we attribute only the atmospheric neutrino anomaly to neutrino oscillation and assume the constant transition probability of νe to explain the solar n...

Is CP Violation Observable in Long Baseline Neutrino Oscillation Experiments ?

We have studied the direct measurements of CP violation in the neutrino oscillations: the difference of the transition probabilities between CP -conjugate channels in the long baseline accelerator experiments. In those experiments, the CP violating effect is not suppressed if the highest neutrino mass scale is taken to be 1 ∼ 10eV, which is appropriate for the cosmological hot dark matter. The ...
