Sensitivity study: Impact of reactor model uncertainty on the measurement of sin(2θ13) in the Double Chooz experiment
نویسنده
چکیده
This paper primarily discusses the results of a sensitivity analysis on the impact of reactor parameters on the ±1σ error of sin(2θ13) = 0.1 in the Double Chooz neutrino experiment and the relevant physical and statistical knowledge. After eight years of data collection, assuming no knowledge of the reactor flux, the value of ±1σFDonly = 1.522, while ±1σFD+ND = 0.0122, and including all previous assumptions, ±1σFDonly = 0.0248, while ±1σFD+ND = 0.0118. Even assuming no knowledge of reactor flux, the second detector provides more accuracy than a single detector relying upon all reactor assumptions.

Review of θ13 and Prospects for Double Chooz
The Double Chooz reactor neutrino experiment will be the next detector to search for a non vanishing θ13 mixing angle with unprecedented sensitivity, which might open the way to unveiling CP violation in the leptonic sector. The measurement of this angle will be based on a precise comparison of the antineutrino spectrum at two identical detectors located at different distances from the Chooz nu...
متن کاملFrom Double Chooz to Triple Chooz — Neutrino Physics at the Chooz Reactor Complex
We discuss the potential of the proposed Double Chooz reactor experiment to measure the neutrino mixing angle sin 2θ13. We especially consider systematical uncertainties and their partial cancellation in a near and far detector operation, and we discuss implications of a delayed near detector startup. Furthermore, we introduce Triple Chooz, which is a possible upgrade scenario assuming a second...
متن کاملReactor Neutrino Experiments
Precisely measuring θ13 is one of the highest priority in neutrino oscillation study. Reactor experiments can cleanly determine θ13. Past reactor neutrino experiments are reviewed and status of next precision θ13 experiments are presented. Daya Bay is designed to measure sin 2θ13 to better than 0.01 and Double Chooz and RENO are designed to measure it to 0.02-0.03. All are heading to full opera...

It has recently been widely recognized that a reactor anti-neutrino disappearance experiment with two or more detectors is one of the most cost-effective ways to extend our reach in sensitivity for the neutrino mixing angle θ13 without ambiguities from CP violation and matter effects[1]. The physics capabilities of a new reactor experiment together with superbeams and neutrino factories have al...
متن کاملReactor Neutrino Experiments with a Large Liquid Scintillator Detector
We discuss several new ideas for reactor neutrino oscillation experiments with a Large Liquid Scintillator Detector. We consider two different scenarios for a measurement of the small mixing angle θ13 with a mobile ν̄e source: a nuclear-powered ship, such as a submarine or an icebreaker, and a land-based scenario with a mobile reactor. The former setup can achieve a sensitivity to sin 2θ13 . 0.0...
