نویسنده
چکیده
In this talk we discuss the possibility to measure CP violation in neutrino oscillation experiments using the neutrino beam with energy which is lower (Eν > ∼ 100 MeV) than the one usually considered (typically > 1 GeV) in accelerator experiments. The advantage of using such lower energy neutrino beam is that despite the smaller detection cross sections, the effect of CP violation is larger and the optimal length of baseline can be rather short, 30-50 km, being free from matter effect contamination.

We review the status of the solutions to neutrino anomalies by flavor-changing as well as flavor-diagonal neutrino interactions. While it is difficult to explain the atmospheric neutrino data the solar neutrino data can be well accounted for by the massless neutrino oscillation induced by such non-standard neutrino interactions. We also discuss the possibility to test such kind of interactions ...

We discuss the isospin symmetry breaking quantity ∆ ±0 ≡ Γ(B ± → ρ ± γ)/2Γ(B 0 → ρ 0 γ)−1, and the direct CP violation in B ± → ρ ± γ within and beyond the standard model. After showing that the leading-order calculation would be a good approximation in such models, we argue that measurements of these quantities would be able to disentagle physics beyond the standard model.

How is CP violation of low energy related to CP violation required from baryon number asymmetry ? We give an example which shows a direct link between CP violation of neutrino oscillation and baryogenesis through leptogenesis. When the sphaleron process is active, the sum of baryon number and lepton number is not a conserved quantity; d(B+L) dt = Anomaly = 0. Therefore, the evolution equation o...

We consider the νμ → νe oscillation measurements that would be possible at upgraded 1 GeV and multi–GeV conventional neutrino sources driven by future megawatt– scale proton drivers. If these neutrino superbeams are used together with detectors that are an order of magnitude larger than those presently foreseen, we find that the sensitivity to νμ → νe oscillations can be improved by an order of...

We investigate the extent to which leptonic CP-violation in (3+2) sterile neutrino models leads to different oscillation probabilities for ν̄μ → ν̄e and νμ → νe oscillations at MiniBooNE. We are using a combined analysis of short-baseline (SBL) oscillation results, including the LSND and null SBL results, to which we impose additional constraints from atmospheric oscillation data. We obtain the f...
