Combined Analysis of Neutrino and Antineutrino Charged Current Inclusive Interactions / Franco-Patino, Juan M (Seville U.) ; Gacino-Olmedo, Alejandro N (Seville U. ; CERN) ; Gonzalez-Rosa, Jesus (Seville U.) ; Dolan, Stephen J (CERN) ; Megias, Guillermo D (Seville U.) ; Munteanu, Laura (CERN) ; Barbaro, Maria B (INFN, Turin ; Turin U.) ; Caballero, Juan A (Seville U.)
This paper presents a combined analysis of muon neutrino and antineutrino charged-current cross sections at kinematics of relevance for the T2K, MINERvA and MicroBooNE experiments. We analyze the sum, difference and asymmetry of neutrino versus antineutrino cross sections in order to get a better understanding of the nuclear effects involved in these processes. [...]

Analysis of T2K and MINER$\nu$A Semi-Inclusive $\nu_\mu$−$^{12}$C Measurements / Franco-Patino, J M (Seville U. ; Turin U. ; INFN, Turin) ; González-Jiménez, R (Madrid U.) ; Dolan, S (CERN) ; Barbaro, M B (Turin U. ; INFN, Turin) ; Caballero, J A (Seville U. ; Granada U., Theor. Phys. Astrophys.) ; Megias, G D (Seville U. ; Tokyo U., ICRR) ; Udias, J M (Madrid U.)
We compare the semi-inclusive C cross-section measurements via T2K and MINERA collaborations with the predictions from the SuSAv2-MEC model implemented in the neutrino event generator GENIE and an unfactorized approach based on the relativistic distorted wave impulse approximation (RDWIA). Results, which include cross-sections as a function of the final muon and proton kinematics as well as correlations between both, show that the agreement with data obtained via the RDWIA approach—which accounts for final-state interactions—matches or improves GENIE-SuSAv2 predictions for very forward angles, where scaling violations are relevant..

Measurements of the $\nu_{\mu}$ and $\bar{\nu}_{\mu}$-induced coherent charged pion production cross cections on $^{12}C$ by the T2K experiment / T2K Collaboration
We report an updated measurement of the $\nu_{\mu}$-induced, and the first measurement of the $\bar{\nu}_{\mu}$-induced coherent charged pion production cross section on $^{12}C$ nuclei in the T2K experiment. This is measured in a restricted region of the final-state phase space for which $p_{\mu,\pi} > 0.2$ GeV, $\cos(\theta_{\mu}) > 0.8$ and $\cos(\theta_{\pi}) > 0.6$, and at a mean (anti)neutrino energy of 0.85 GeV using the T2K near detector.

Parametrized uncertainties in the spectral function model of neutrino charged-current quasielastic interactions for oscillation analyses / Chakrani, J. (LLR, Palaiseau) ; Dolan, S. (CERN) ; Buizza Avanzini, M. (LLR, Palaiseau) ; Ershova, A. (IRFU, Saclay) ; Koch, L. (Mainz U., Inst. Phys.) ; McFarland, K. (Rochester U.) ; Megias, G.D. (Seville U.) ; Munteanu, L. (CERN) ; Pickering, L. (Royal Holloway, U. of London) ; Skwarczynski, K. (Warsaw, Inst. Nucl. Studies) et al.
A substantial fraction of systematic uncertainties in neutrino oscillation experiments stem from the lack of precision in modeling the nuclear target in neutrino-nucleus interactions. Whilst this has driven significant progress in the development of improved nuclear models for neutrino scattering, it is crucial that the models used in neutrino data analyses be accompanied by parameters and associated uncertainties that allow the coverage of plausible nuclear physics.

Muon neutrino and antineutrino disappearance probabilities are identical in the standard three-flavor neutrino oscillation framework, but CPT violation and non-standard interactions can violate this symmetry. In this work we report the measurements of $\sin^{2} \theta_{23}$ and $\Delta m_{32}^2$ independently for neutrinos and antineutrinos. [...]

(Seville U. ; IRFU, Saclay, DPP ; Granada U.) ; Megias, G.D. (Seville U. ; IRFU, Saclay, DPP)
In this work we present a comparison of semi-inclusive muon and electron neutrino cross sections with $^{40}$Ar target measured by the MicroBooNE Collaboration with the predictions of an unfactorized model based on the relativistic distorted wave impulse approximation (RDWIA) and the SuSAv2-MEC model implemented in the neutrino event generator GENIE. The predictions based on the RDWIA approach, with a realistic description of the initial state and a phenomenological relativistic complex optical potential for the description of final state interactions, better describe the measured cross sections than GENIE-SuSAv2 and RDWIA with a purely real potential..

First measurement of muon neutrino charged-current interactions on hydrocarbon without pions in the final state using multiple detectors with correlated energy spectra at T2K / T2K Collaboration
This paper reports the first measurement of muon neutrino charged-current interactions without pions in the final state using multiple detectors with correlated energy spectra at T2K. The data was collected on hydrocarbon targets using the off-axis T2K near detector (ND280) and the on-axis T2K near detector (INGRID) with neutrino energy spectra peaked at 0.6 GeV and 1.1 GeV respectively.

The T2K experiment presents new measurements of neutrino oscillation parameters using $19.7(16.3)\times10^{20}$ protons on target (POT) in (anti-)neutrino mode at the far detector (FD). Compared to the previous analysis, an additional $4.7\times10^{20}$ POT neutrino data was collected at the FD. [...]

We present a complete comparison of semi-inclusive $\nu_\mu$-$^{12}$C cross-section measurements by T2K and MINER$\nu$A collaborations with the predictions from the SuSAv2-MEC model implemented in the neutrino-nucleus event generator GENIE and an unfactorized approach based on the relativistic distorted wave impulse approximation (RDWIA). Results, that include cross sections as function of the final muon and proton kinematics and correlations between both, show that the agreement with data obtained by the RDWIA approach, that accounts for final-state interactions, matches or improves GENIE-SuSAv2 predictions for very forward angles where scaling violations are relevant..
