New Results from the Double Chooz Experiment
Buck, Christian
The Double Chooz reactor antineutrino experiment presents latest results using data taken with its two detectors. The average baseline to the two reactor cores of the nuclear power plant in Chooz, France, is about 400 m for the near and about 1 km for the far detector. An identical detector design and almost isoflux conditions allow for a precision measurement of the neutrino mixing angle θ13. Unique techniques in the selection of inverse beta decay events and background discrimination are shown, optimized for high antineutrino detection efficiency and improved systematics.
Furthermore, the measured energy spectrum of the reactor antineutrinos is compared to predictions. The observed spectral distortions are discussed. Our recent analysis of the near Double Chooz detector data also allows for a precise determination of the mean reactor neutrino interaction rate. The detected antineutrino rate is compared to the results of other experiments and prediction models.
