Beneficial effects of biochar to contaminated soils on the bioavailability of Cd, Pb and Zn and the biomass production of rapeseed (Brassica napus L.).
The observation of the recent electron neutrino appearance in a muon neutrino
beam and the high-precision measurement of the mixing angle have
led to a re-evaluation of the physics potential of the T2K long-baseline
neutrino oscillation experiment. Sensitivities are explored for CP violation in
neutrinos, non-maximal , the octant of , and
the mass hierarchy, in addition to the measurements of ,
, and , for various combinations of
-mode and -mode data-taking.
With an exposure of ~protons-on-target, T2K can achieve
1- resolution of 0.050(0.054) on and
on for 100\%(50\%)
neutrino beam mode running assuming and eV. T2K will have sensitivity to the
CP-violating phase at 90\% C.L. or better over a significant
range. For example, if is maximal (i.e
=) the range is
for normal hierarchy and for inverted
hierarchy. When T2K data is combined with data from the NOA experiment,
the region of oscillation parameter space where there is sensitivity to observe
a non-zero is substantially increased compared to if each
experiment is analyzed alone.Comment: 40 pages, 27 figures, accepted by PTE
Recent Results from the T2K Experiment
The Tokai to Kamioka (T2K) experiment studies neutrino oscillations using a beam of muon neutrinos produced by an accelerator. The neutrinos travel from J-PARC on the east coast of Japan and are detected 295 kilometers further away in the Super-Kamiokande detector. A complex of near detectors located 280 meters away from the neutrino production target is used to better characterize the neutrino beam and reduce systematic uncertainties. The experiment aims at measuring electronic neutrino appearance (νμ→νe oscillation) to measure the neutrino mixing angle θ13, and muon neutrino disappearance to measure the neutrino mixing angleθ23 and mass splitting |Δm232|. We report here electron neutrino appearance results using three years of data, recorded until the 2012 summer, as well as muon neutrino disappearance results based on the data coming from the first two years of the experiment
