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...

We present a search for Lorentz violation with 8249 candidate electron antineutrino events taken by the Double Chooz experiment in 227.9 live days of running. This analysis, featuring sidereal time dependence events, is first test invariance using reactor-based source. No variation data and disappearance results are consistent independent oscillations. Under Standard-Model Extension, we set limits on 14 violating coefficients associated transitions between tau flavor, two competitive muon flavor.
Abstract In this paper, we review scientific opportunities and challenges related to detection reconstruction of low-energy (less than 100 MeV) signatures in liquid argon time-projection chamber (LArTPC) neutrino detectors. LArTPC detectors designed for performing precise long-baseline oscillation measurements with GeV-scale accelerator beams also have unique sensitivity a range physics astrophysics via event features at below the few tens MeV range. addition, are an integral part...

A 10 kilo-tonne dual-phase liquid argon TPC is one of the detector options considered for Deep Underground Neutrino Experiment (DUNE). The technology relies on amplification ionisation charge in ultra-pure vapour and offers several advantages compared to traditional single-phase TPCs. 4.2 tonne prototype, largest its kind, with an active volume \three has been constructed operated at CERN. In this paper we describe detail experimental setup components as well report operation experience. We...
Liquid argon time projection chambers (TPC) are widely used in neutrino oscillation and dark matter experiments. Detection of scintillation light liquid TPC's is challenging because its short wavelength, the VUV range, cryogenic temperatures (~86 K) at which sensors must operate. Wavelength shifters (WLS) typically needed to take advantage high Photon Efficiency (PDE) visible range most photondetectors. The Hamamatsu VUV4 S13370--6075CN SiPMs can directly detect without use WLS, main benefit...
