Double Chooz: Neutron Capture Analysis

This Paper describes the work done analyzing the neutron capture on the Double Chooz detector located at northern France; this detector is searching for the oscillation of electron antineutrinos produced by a nuclear power plant. Neutrinos and also antineutrinos, of which there are three types, have been found to oscillate from one type to another. But these oscillations are governed by several parameters of which one of them have not been yet measured, this parameters is the mixing angle θ!". The study of neutron capture in the Double Chooz is very important in the search of this parameter, and it is also important for the well calibration of the Double Chooz detector.
