Measurement of d2σ/d|q→|dEavail in charged current νμ -nucleus interactions at ⟨Eν⟩=1.86 GeV using the NOvA Near Detector

M. A. Acero, B. S. Acharya, P. Adamson, Leonidas Aliaga et autres

Double- and single-differential cross sections for inclusive charged-current νμ -nucleus scattering are reported for the kinematic domain 0 to 2 GeV/c in three-momentum transfer and 0 to 2 GeV in available energy, at a mean νμ energy of 1.86 GeV. The measurements …

Monte Carlo method for constructing confidence intervals with unconstrained and constrained nuisance parameters in the NOvA experiment

M. A. Acero, B. S. Acharya, P. Adamson, Leonidas Aliaga et autres

Abstract Measuring observables to constrain models using maximum-likelihood estimation is fundamental to many physics experiments. Wilks' theorem provides a simple way to construct confidence intervals on model parameters, but it only applies under certain conditions. These conditions, such as nested hypotheses and …

Measurement of the double-differential cross section of muon-neutrino charged-current interactions with low hadronic energy in the NOvA Near Detector

M. A. Acero, B. S. Acharya, P. Adamson, Leonidas Aliaga et autres

The NOvA collaboration reports cross-section measurements for $ν_μ$ charged-current interactions with low hadronic energy (maximum kinetic energy of 250 MeV for protons and 175 MeV for pions) in the NOvA Near Detector. The results are presented as a double-differential cross section as …

Search for $CP$-Violating Neutrino Nonstandard Interactions with the NOvA Experiment

NOvA Collaboration, M. A. Acero, B. S. Acharya, P. Adamson et autres

This Letter reports a search for charge-parity ($CP$) symmetry violating nonstandard interactions (NSI) of neutrinos with matter using the NOvA Experiment, and examines their effects on the determination of the standard oscillation parameters. Data from $ν_μ(\barν_μ)\rightarrowν_μ(\barν_μ)$ and $ν_μ(\barν_μ)\rightarrowν_{e}(\barν_{e})$ oscillation channels are used …

Measurement of the double-differential muon-neutrino charged-current inclusive cross section in the NOvA near detector

M. A. Acero, P. Adamson, Leonidas Aliaga, Н. Анфимов et autres

We report cross-section measurements of the final-state muon kinematics for ${\ensuremath{\nu}}_{\ensuremath{\mu}}$ charged-current interactions in the NOvA near detector using an accumulated $8.09\ifmmode\times\else\texttimes\fi{}{10}^{20}$ protons on target in the NuMI beam. We present the results as a double-differential cross section in the observed outgoing …

Measurement of the ν e -Nucleus Charged-Current Double-Differential Cross Section at ⟨ E ν ⟩ = 2.4 GeV Using NOvA

M. A. Acero, P. Adamson, Leonidas Aliaga, Н. Анфимов et autres

The inclusive electron neutrino charged-current cross section is measured in the NOvA near detector using 8.02×10^{20} protons-on-target in the NuMI beam. The sample of GeV electron neutrino interactions is the largest analyzed to date and is limited by ≃17% systematic rather than …

Search for Active-Sterile Antineutrino Mixing Using Neutral-Current Interactions with the NOvA Experiment

M. A. Acero, P. Adamson, L. Aliaga, N. Anfimov et autres

This Letter reports results from the first long-baseline search for sterile antineutrinos mixing in an accelerator-based antineutrino-dominated beam. The rate of neutral-current interactions in the two NOvA detectors, at distances of 1 and 810 km from the beam source, is analyzed using …

Extended search for supernovalike neutrinos in NOvA coincident with LIGO/Virgo detections

M. A. Acero, P. Adamson, Leonidas Aliaga, Н. Анфимов et autres

A search is performed for supernovalike neutrino interactions coincident with 76 gravitational wave events detected by the LIGO/Virgo Collaboration. For 40 of these events, full readout of the time around the gravitational wave is available from the NOvA Far Detector. For these …

Analysis of reactive bromine production and ozone depletion in the Arctic boundary layer using 3-D simulations with GEM-AQ: inference from synoptic-scale patterns

Kenjiro Toyota, John C. McConnell, Alexandru Lupu, Lori Neary et autres

Abstract. Episodes of high bromine levels and surface ozone depletion in the springtime Arctic are simulated by an online air-quality model, GEM-AQ, with gas-phase and heterogeneous reactions of inorganic bromine species and a simple scheme of air-snowpack chemical interactions implemented for this …
