New Measurements of Reactor Disappearance with the Double Chooz Far Detector

We present an update on the results of the Double Chooz experiment. Double Chooz searches for the neutrino mixing angle, θ13, in the three-neutrino mixing matrix via the disappearance of produced by the dual 4.27 GW/th Chooz B Reactors. Here we discuss updated oscillation fit results using both the rate and the shape of the anti-neutrino energy spectrum. In the most recent oscillation analysis we included data with neutron captures on Gadolinium and Hydrogen along with the reactor off data that we collected. This is an important step in our multi-year program to establish the value of θ13.
