    Status of FNAL SciBooNE experiment

    SciBooNE is a new experiment at FNAL which will make precision neutrino-nucleus cross section measurements in the one GeV region. These measurements are essential for the future neutrino oscillation experiments. We started data taking in the antineutrino mode on June 8, 2007, and collected 5.19 \times 10^{19} protons on target (POT) before the accelerator shutdown in August. The first data from SciBooNE are reported in this article.Comment: 3 pages, 3 figures.

    Status and perspectives of short baseline studies

    Full text link
    The study of flavor changing neutrinos is a very active field of research. I will discuss the status of ongoing and near term experiments investigating neutrino properties at short distances from the source. In the next few years, the Double Chooz, RENO and Daya Bay reactor neutrino experiments will start looking for signatures of a non-zero value of the mixing angle θ13\theta_{13} with much improved sensitivities. The MiniBooNE experiment is investigating the LSND anomaly by looking at both the νμνe\nu_{\mu} \to \nu_{e} and νˉμνˉe\bar{\nu}_{\mu} \to \bar{\nu}_{e} appearance channels. Recent results on cross section measurements will be discussed briefly.Comment: 6 pages, 2 figures, to appear in the proceedings of the 11th International Conference on Topics in Astroparticle and Underground Physics (TAUP 2009), Rome, Italy, 1-5 July 200

    On the impact of systematical uncertainties for the CP violation measurement in superbeam experiments

    Superbeam experiments can, in principle, achieve impressive sensitivities for CP violation in neutrino oscillations for large θ13\theta_{13}. We study how those sensitivities depend on assumptions about systematical uncertainties. We focus on the second phase of T2K, the so-called T2HK experiment, and we explicitly include a near detector in the analysis. Our main result is that even an idealised near detector cannot remove the dependence on systematical uncertainties completely. Thus additional information is required. We identify certain combinations of uncertainties, which are the key to improve the sensitivity to CP violation, for example the ratio of electron to muon neutrino cross sections and efficiencies. For uncertainties on this ratio larger than 2%, T2HK is systematics dominated. We briefly discuss how our results apply to a possible two far detector configuration, called T2KK. We do not find a significant advantage with respect to the reduction of systematical errors for the measurement of CP violation for this setup.Comment: 30 pages, 10 figures, version accepted for publication in JHE
