The Double Chooz experiment has determined the value of neutrino oscillation parameter $\theta_{13}$ from an analysis inverse beta decay interactions with neutron capture on hydrogen. This uses a three times larger fiducial volume than standard assessment, which is restricted to region doped gadolinium (Gd), yielding exposure 113.1 GW-ton-years. data sample used in this distinct that Gd analysis, and systematic uncertainties are also largely independent, some exceptions, such as reactor flux...
