Results from the Double Chooz experiment

Abstract

The Double Chooz experiment is a neutrino experiment using electron antineutrinos produced by reactor cores of the Chooz nuclear power plant. The main purpose of the experiment is to measure the neutrino mixing angle $\theta_{13}$. Non-zero mixing angle results in a disappearance of electron antineutrinos. The experiment consists of two detectors. The far one is located at a distance of 1050\,m from the reactor cores to measure the disappearance of electron antineutrinos, while the near one is located at a distance of 400\,m from the reactor cores to measure the original neutrino flux from the reactor cores. The data taking started in 2011 at the far detector, and in 2014 at the near detector. In this presentation, the latest results from the Double Chooz experiment are shown. The main result of the neutrino mixing angle $\theta_{13}$ value is $\sin^{2}2\theta_{13}=0.119\pm0.016$.
