Abstract
The reactor ¯νe disappearance experiment Double Chooz, located in France near the power plant of Chooz, has as main goal the measurement of the θ13 mixing angle. For the first time, in 2011, the experimental results gave an indication for a non-zero value of such an oscillation parameter. The mixing angle was successively measured using only the far detector finding the best fit value of sin2(2θ13) = 0.090+0.033−0.029. The near detector started data taking in December 2014 and it will allow to reduce the systematic errors so far dominated by the reactor flux uncertainty. In this paper a review of the experiment is presented focusing on the so-called Gadolinium-III results (Double Chooz Collaboration (Abe Y. et al.), JHEP, 10(2014) 086; 02 (2015) 074). Furthermore additional physics measurements are presented such as the capability of Double Chooz to identify the ortho-positronium state on event by event basis.
