First measurement of θ[subscript 13] from delayed neutron capture on hydrogen in the Double Chooz experiment
The Double Chooz experiment has determined the value of the neutrino oscillation parameter θ[subscript 13] from an analysis of inverse beta decay interactions with neutron capture on hydrogen. This analysis uses a three times larger fiducial volume than the standard Double Chooz assessment, which i...

| description | The Double Chooz experiment has determined the value of the neutrino oscillation parameter θ[subscript 13] from an analysis of inverse beta decay interactions with neutron capture on hydrogen. This analysis uses a
three times larger fiducial volume than the standard Double Chooz assessment, which is restricted to a region doped with gadolinium (Gd), yielding an exposure of 113.1 GW-ton-years. The data sample used
in this analysis is distinct from that of the Gd analysis, and the systematic uncertainties are also largely independent, with some exceptions, such as the reactor neutrino flux prediction. A combined rate- and energy-dependent fit finds sin[superscript 2] 2θ[subscript 13] = 0.097 ± 0.034 (stat.) ± 0.034 (syst.), excluding the no-oscillation hypothesis at 2.0σ. This result is consistent with previous measurements of sin[superscript 2] 2θ[subscript 13]. |
