چکیده
In the case of large 1-3 mixing angle as sin 2θ13 ≥ 0.03, we investigate the possibility for measuring the leptonic CP phase by using only νμ → νμ oscillations independently of νμ → νe oscillations. As the result, we find that the CP phase can be measured best around the energy E = 0.43GeV and the baseline length L = 5000km without strongly depending on the uncertainties of other parameters. In this region, the CP phase effect remains even after averaging over neutrino energy. We also find that there is the CP sensitivity even in the short baseline length L ≤ 1000km if ∆m231 is determined with the uncertainty of about 0.1%. In the T2KK experiment, we explore the possibility for determining ∆m231 by using one baseline from Tokai to Korea and then measuring the CP phase by using the baseline to Kamioka. As the result, we find that some information of the CP phase can be obtained from both measurements.

We discuss three applications of NJLand PNJL-like models to assess aspects of the QCD phase diagram: First, we study the effect of mesonic correlations on the pressure below and above the finite temperature phase transition within a nonlocal PNJL model beyond the mean-field approximation. Second, we reconstruct the phase boundary of an NJL model from a Taylor expansion of the chiral susceptibil...

The ratio RK = Γ(K± → e±ν)/Γ(K± → μ±ν) provides a very powerful probe for the weak interactions structure. This ratio of decay rates is calculated with very high precision within the Standard Model but the corrections due to the presence of New Physics could be as high as 3%. The data obtained by the NA48 experiment at the CERN SPS accelerator during a 56 hours special run in 2004 has been anal...

Experiments are planned to improve the sensitivity of μ − e conversion from the current ∼ 10 to ∼ 10 − 10. If the muon (bound to the nucleus) could be polarised, a spin asymmetry of the final state electron is sensitive to CP violating phases on lepton flavour violating operators. This is similar to extracting phases from asymmetries in the final state spin and phase space distributions of μ → ...
