No full textMeasurement of quasielastic-like neutrino scattering at ∼3.5 GeV on a hydrocarbon target
No full textMINERvA presents a new analysis of neutrino induced quasielastic-like interactions in a hydrocarbon tracking target. We report a double-differential cross section using the muon transverse and longitudinal momentum. In addition, differential cross sections as a function of the square of the four-momentum transferred and the neutrino energy are calculated using a quasielastic hypothesis. Finally, an analysis of energy deposited near the interaction vertex is presented. These results are compared to modified genie predictions as well as a NuWro prediction. All results use a data set produced by 3.34×1020 protons on target creating a neutrino beam with a peak energy of approximately 3.5 GeV. .Consejo Nacional de Ciencia, Tecnología e Innovación Tecnológica - Concyte
Measurement of nuclear effects in neutrino interactions with minimal dependence on neutrino energy
No full textWe present a phenomenological study of nuclear effects in neutrino charged-current interactions, using transverse kinematic imbalances in exclusive measurements. Novel observables with minimal dependence on neutrino energy are proposed to study quasielastic scattering and especially resonance production. They should be able to provide direct constraints on nuclear effects in neutrino- and antineutrino-nucleus interactions

M. Ziembicki, M. Zito, S. ZsoldosWe report measurements by the T2K experiment of the parameters θ23 and Δm2
32, which govern the
disappearance of muon neutrinos and antineutrinos in the three-flavor PMNS neutrino oscillation model at
T2K’s neutrino energy and propagation distance. Utilizing the ability of the experiment to run with either a
mainly neutrino or a mainly antineutrino beam, muon-like events from each beam mode are used to
measure these parameters separately for neutrino and antineutrino oscillations. Data taken from 1.49 × 1021
protons on target (POT) in neutrino mode and 1.64 × 1021 POT in antineutrino mode are used. The best-fit

10−3 eV2=c4 for neutrinos (antineutrinos). No significant differences between the values of the parameters
describing the disappearance of muon neutrinos and antineutrinos were observed. An analysis using an
effective two-flavor neutrino oscillation model where the sine of the mixing angle is allowed to take
nonphysical values larger than 1 is also performed to check the consistency of our data with the three-flavor
model. Our data were found to be consistent with a physical value for the mixing angle
Neutron measurements from antineutrino hydrocarbon reactions
No full textCharged-current antineutrino interactions on a hydrocarbon scintillator in the MINERvA detector are used to study activity from their final-state neutrons. To ensure that most of the neutrons are from the primary interaction, rather than hadronic reinteractions in the detector, the sample is limited to momentum transfers below 0.8 GeV/c. From 16 129 interactions, 15 246 neutral particle candidates are observed. The reference simulation predicts 64% of these candidates are due to neutrons from the antineutrino interaction directly but also overpredicts the number of candidates by 15% overall. This discrepancy is beyond the standard uncertainty estimates for models of neutrino interactions and neutron propagation in the detector. We explore these two aspects of the models using the measured distributions for energy deposition, time of flight, position, and speed. We also use multiplicity distributions to evaluate the presence of a two-nucleon knockout process. These results provide critical new information toward a complete description of the hadronic final state of neutrino interactions, which is vital to neutrino oscillation experiments

(T2K Collaboration)This paper reports the first simultaneous measurement of the double differential muon neutrino chargedcurrent
cross section on oxygen and carbon without pions in the final state as a function of the outgoing
muon kinematics, made at the ND280 off-axis near detector of the T2K experiment. The ratio of the oxygen
and carbon cross sections is also provided to help validate various models’ ability to extrapolate between
carbon and oxygen nuclear targets, as is required in T2K oscillation analyses. The data are taken using a
neutrino beam with an energy spectrum peaked at 0.6 GeV. The extracted measurement is compared with
the prediction from different Monte Carlo neutrino-nucleus interaction event generators, showing particular
model separation for very forward-going muons. Overall, of the models tested, the result is best described
using local Fermi gas descriptions of the nuclear ground state with RPA suppression
