abstract

The first results from Double Chooz with 100 days of data measured $\sin^2(2\theta_{13}) = 0.086 \pm 0.051$. Backgrounds contribute significantly to the systematic uncertainty budget. Using the incoming neutrino directionality we will attempt to further separate the inverse beta decay signal from backgrounds. The CHOOZ experiment completed a similar analysis and found that the neutrino source can be located to within a cone of half-aperture of 18 degrees at the 68% C.L. We study the possible improvement of this result by Double Chooz.

  1. Enhancing Angular Sensitivity of Segmented Antineutrino Detectors for Reactor Monitoring

    hep-ex 2026-03 conditional novelty 5.0 of 10

    A Frobenius-norm template-matching algorithm estimates antineutrino direction from neutron-capture patterns in segmented detectors, with an optimal segment size near the mean neutron track length (~70 mm) at low counts.
