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...
This paper presents a summary of beam-induced backgrounds observed in the ATLAS detector and discusses methods to tag remove background contaminated events data.

As long-baseline neutrino experiments enter the precision era, difficulties associated with understanding interaction cross sections on atomic nuclei are expected to limit experimental sensitivities oscillation parameters. In particular, ability relate observables energy in previous has relied solely theoretical models of neutrino-nucleus interactions, which currently suffer from very large uncertainties.
