MEASUREMENT OF sin 2 2θ13 BY REACTOR EXPERIMENTS AND ITS SENSITIVITY ∗
نویسنده
چکیده
Reactor experiments offer a promising way to determine θ13 and are free from parameter degeneracies in neutrino oscillations. It is described how reactor measurements of sin 2θ13 can be improved by a near-far detector complex. The experimental lower bound is derived on the sensitivity to sin 2θ13 & 0.02 based on the rate analysis, and an idea is given which may enable us to circumvent this bound. It is shown that in the Kashiwazaki-Kariwa plan (KASKA) the sensitivity to sin 2θ13 is approximately 0.02.

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 کاملUnderstanding the Determination of Neutrino Mixing Angles With ν̄es from Nuclear Reactors
Since the proposition of the neutrino as a fundamental particle in 1930, it has proved to be difficult to study, primarily because of its relatively rare interactions with matter at naturally occurring energies. Deducing the neutrino’s flavor mixing properties, then, is an exercise in precision measurement and clever experimental design. Nuclear reactor provide an intense, well known source of ...

متن کاملTheta 13 Determination with Nuclear Reactors F. Dalnoki-Veress for the Double-Chooz Project
Recently there has been a lot of interest around the world in the use of nuclear reactors to measure θ13 , the last undetermined angle in the 3-neutrino mixing scenario. In this paper the motivations for θ13 measurement using short baseline nuclear reactor experiments are discussed. The features of such an experiment are described in the context of Double Chooz, which is a new project planned t...
متن کاملCp Violation in Neutrino Oscillations without Antineutrinos: Energy Dependence
The next generation of long baseline neutrino oscillation experiments will aim at determining the unknown mixing angle θ13, the type of neutrino mass hierarchy and CP-violation. We discuss the separation of these properties by means of the energy dependence of the oscillation probability and we consider an hybrid setup which combines the electron capture and the β decay from the same radioactiv...
