Prospects for antineutrino running at MiniBooNE
No full textMiniBooNE began running in antineutrino mode on 19 January, 2006. We describe the sensitivity of MiniBooNE to LSND-like {bar {nu}}{sub e} oscillations and outline a program of antineutrino cross-section measurements necessary for the next generation of neutrino oscillation experiments. We describe three independent methods of constraining wrong-sign (neutrino) backgrounds in an antineutrino beam, and their application to the MiniBooNE antineutrino analyses
Charged current single pion cross section measurement at MiniBooNE
No full textWe present MiniBooNE's preliminary {nu}{sub {mu}} CC1{pi}{sup +} cross section measurement, calculated using the ratio of CC1{pi}{sup +} to CCQE events. We find the inclusive CC1{pi}{sup +} measurement to be below the nuance [1] and NEUGEN [2] expectations

Measuring nu(mu) charged-current muon neutrino interactions in MiniBooNE
No full textMiniBooNE seeks to confirm or refute the LSND {bar {nu}}{sub {mu}} {yields} {bar {nu}}{sub e} oscillation signal with high statistical significance and different systematics. MiniBooNE has accumulated the world's largest {approx} 1 GeV neutrino data set. MiniBooNE employs a cosmic muon calibration system to study the reconstruction of the energies and directions of muons in the detector. Progress of measurements of the {nu}{sub {mu}} charged-current quasi-elastic and single pion production cross sections are presented
Study of neutrino-induced neutral current neutral pion production in the T2K near detector
No full textThe T2K experiment is a long baseline neutrino oscillation experiment. The
most intense accelerator muon neutrino beam ever built is produced at the
J-PARC facility in Tokai, located on the east coast of Japan, and directed
(2.5 [degrees] off -axis) toward the Super-Kamiokande water Cherenkov detector, located
295 km away in the mountains of western Japan.
For the current T2K [Symbol appears here. To view, please open pdf attachment]e appearance analysis, 23% of the background at Super-
Kamiokande is from neutral current interactions that produce one π0 in the final state (NC 1π0). This study uses ND280 Run 2 data totalling 7.832 x 10 [to the power of 19] POT
and selects neutrino-induced NC 1π0 interactions in FGD1 and FGD2 where
both π0 decay photons convert in the barrel and downstream ECAL.
Overall, neglecting photon reconstruction efficiency, an efficiency of 22% and
purity of 16% is obtained. For the case where both π0 decay photons convert in
the downstream (barrel) ECAL an efficiency of 33% (12%) and purity of 43%
(9%) is achieved. When one photon converts in the barrel ECAL and the other
in the downstream ECAL the efficiency (purity) is 29% (16%).
Systematic uncertainties arising from cross-section model parameters and final state interactions, the neutrino flux prediction and the shape discrepancy between
ECAL variables in data and MC are evaluated. The predicted total number
of events when both photons convert in the downstream and barrel ECAL is
7.1± 2.3 (syst)± 0.5 (stat) and 31.6± 8.9 (syst) ±1.2 (stat), respectively. Whereas
when one decay photon is reconstructed in the barrel ECAL and the other in the
downstream ECAL the expected number of events is 38.1± 8.7 (syst) ±1.3 (stat).
The selected number of events in data is 5, 22 and 31, respectively, which agrees
with the prediction within errors.
The calibration of the time offsets for the barrel and downstream ECAL is
also presented in this thesis. The application of this calibration reduces the
timing resolution from 9 ns to approximately 2.5 ns, for high charge hits.Open Acces

Prospects for neutrino astrophysics with Hyper-Kamiokande
No full textHyper-Kamiokande is a multi-purpose next generation neutrino experiment. The detector is a two-layered cylindrical shape ultra-pure water tank, with its height of 64 m and diameter of 71 m. The inner detector will be surrounded by tens of thousands of twenty-inch photosensors and multi-PMT modules to detect water Cherenkov radiation due to the charged particles and provide our fiducial volume of 188 kt. This detection technique is established by Kamiokande and Super-Kamiokande. As the successor of these experiments, Hyper-K will be located deep underground, 600 m below Mt. Tochibora at Kamioka in Japan to reduce cosmic-ray backgrounds. Besides our physics program with accelerator neutrino, atmospheric neutrino and proton decay, neutrino astrophysics is an important research topic for Hyper-K. With its fruitful physics research programs, Hyper-K will play a critical role in the next neutrino physics frontier. It will also provide important information via astrophysical neutrino measurements, i.e., solar neutrino, supernova burst neutrinos and supernova relic neutrino. Here, we will discuss the physics potential of Hyper-K neutrino astrophysics. © Copyright owned by the author(s)
