Abstract The ICARUS liquid argon time projection chamber (LArTPC) neutrino detector has been taking physics data since 2022 as part of the Short-Baseline Neutrino (SBN) Program. This paper details equalization response to charge in (TPC), well data-driven tuning simulation ionization signals and electronics noise. procedure removes non-uniformities TPC space time. work leverages copious number cosmic ray muons available at surface. signal shape applies a novel that tunes match what is...
Abstract This paper reports on a measurement of electron-ion recombination in liquid argon the ICARUS time projection chamber (LArTPC). A clear dependence angle ionizing particle track relative to drift electric field is observed. An ellipsoid modified box (EMB) model describes data across all measured angles. These measurements are used for calorimetric energy scale calibration TPC, which also presented. The impact EMB studied identification, as well muon and proton measurements. Accounting...
The CONNIE detector prototype is operating at a distance of 30 m from the core 3.8 GW$_{\rm th}$ nuclear reactor with goal establishing Charge-Coupled Devices (CCD) as new technology for detection coherent elastic neutrino-nucleus scattering. We report on results engineering run an active mass 4 g silicon. CCD array described, and performance observed during first year discussed. A compact passive shield was deployed detector, producing order magnitude reduction in background rate. remaining...
The CONNIE experiment uses fully depleted, high resistivity CCDs as particle detectors in an attempt to measure for the first time Coherent Neutrino-Nucleus Elastic Scattering of antineutrinos from a nuclear reactor with silicon nuclei. This talk, given at XV Mexican Workshop on Particles and Fields (MWPF), discussed potential perform this measurement, installation progress Angra dos Reis power plant, well plans future upgrades.
We present measurements of radioactive contamination in the high-resistivity silicon charge-coupled devices (CCDs) used by DAMIC experiment to search for dark matter particles. Novel analysis methods, which exploit unique spatial resolution CCDs, were developed identify $\alpha$ and $\beta$ Uranium thorium CCD bulk was measured through spectroscopy, with an upper limit on $^{238}$U ($^{232}$Th) decay rate 5 (15) kg$^{-1}$ d$^{-1}$ at 95% CL. also searched pairs spatially correlated electron...
Future long-baseline experiments will measure neutrino oscillation properties with unprecedented precision and search for clear signatures of $CP$ violation in the leptonic sector. Near detectors can neutrino-electron scattering high statistics, giving chance its precise measurement. We study, this work, expectations measurement radiative corrections process. focus on determination contributions that are exclusive to channels, particularly charge radius. illustrate how perspectives a first...
DAMIC (Dark Matter in CCDs) is an experiment searching for dark matter particles employing fully-depleted charge-coupled devices. Using the bulk silicon which composes detector as target, we expect to observe coherent WIMP-nucleus elastic scattering. Although located SNOLAB laboratory, 2 km below surface, CCDs are not completely free of radioactive contamination, particular coming from radon daughters or itself. We present novel techniques measurement contamination and on surface CCDs....

We consider the possible effect of Standard Model Extension (SME) coefficient $(a_L)^Z$ in neutrino propagation and discuss how this can affect DUNE limits on $(a_L)^T$ found elsewhere. Based an analysis that considers both coefficients, we find new constraints for them coming from DUNE. Furthermore, investigate correlations standard oscillation parameters, leptonic $CP-$violating phase, $\delta_{CP}$, atmospheric mixing angle, $\sin^2 \theta_{23}$, with respect to SME coefficients $(a_L)^Z$.
