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. Proceedings of the 10th International Conference

Status and perspectives of short baseline studies
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
with much improved sensitivities. The MiniBooNE experiment is investigating the
LSND anomaly by looking at both the and
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

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 . 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
