“…A precise measurement of the oscillation parameters relies on the understanding of the incoming neutrino beam flux, of the scattering of neutrinos with nucleons, and of the nuclear medium effects in the nucleus. The systematic uncertainties arising from neutrino-nucleus interactions, especially those related to nuclear effects, are currently one of the limiting factors for oscillation measurements [13] in T2K [14] and NOvA [15], and will become the dominant uncertainties for future long-baseline experiments, such as DUNE [12] and HyperKamiokande [16].…”

This paper reports measurements of final-state proton multiplicity, muon and proton kinematics, and their correlations in charged-current pionless neutrino interactions, measured by the T2K ND280 near detector in its plastic scintillator (C 8 H 8 ) target. The data were taken between years 2010 and 2013, corresponding to approximately 6 × 10 20 protons on target. Thanks to their exploration of the proton kinematics and of imbalances between the proton and muon kinematics, the results offer a novel probe of the nuclear-medium effects most pertinent to the (sub-)GeV neutrino-nucleus interactions that are used in accelerator-based long-baseline neutrino oscillation measurements. These results are compared to many neutrino-nucleus interaction models which all fail to describe at least part of the observed phase space. In case of events without a proton above a detection threshold in the final state, a fully consistent implementation of the local Fermi gas model with multinucleon interactions gives the best description of the data. In the case of at least one proton in the final state, the spectral function model agrees well with the data, most notably when measuring the kinematic imbalance between the muon and the proton in the plane transverse to the incoming neutrino. Within the models considered, only the existence of multinucleon interactions are able to describe the extracted cross section within regions of high transverse kinematic imbalance. The effect of final-state interactions is also discussed.

“…The modelling of neutrino-nucleus interactions in the one-to-few GeV region is one of the most complicated issues facing current long-baseline neutrino oscillation measurements (T2K, NOVA) and is expected to be one of the limiting factors for the sensitivity of the future experiments such as DUNE and T2HK [1]. A key systematic uncertainty arises from the description of multinucleon correlations in the initial state which may induce 2-particle-2-hole (2p2h) final states.…”

Implementation of the SuSAv2-meson exchange current 1p1h and 2p2h models in GENIE and analysis of nuclear effects in T2K measurements

We first present the implementation and validation of the SuSAv2-MEC 1p1h and 2p2h models in the GENIE neutrino-nucleus interaction event generator and a comparison of the subsequent predictions to measurements of lepton and hadron kinematics from the T2K experiment. These predictions are also compared to those of other available models in GENIE. We additionally compare the semi-inclusive predictions of the implemented 1p1h model to those of the microscopic model on which SuSAv2 is based -Relativistic Mean Field (RMF) -to begin to test the validity of widelyused 'factorisation' assumptions employed by generators to predict hadron kinematics from inclusive input models. The results highlight that a more precise treatment of hadron kinematics in generators is essential in order to attain the few-% level uncertainty on neutrino interactions necessary for the next generation of accelerator-based long-baseline neutrino oscillation experiments.

“…Describing the fundamental constituents of the elements that make up the world we know, nPDFs are interesting in their own right. Furthermore, they are a key input for the theoretical interpretations of a large variety of ongoing and future experiments on high-energy nuclear physics, such as heavy-ion (A þ A) and proton-nucleus (p + A) collisions at RHIC [7] and the LHC [8][9][10], deep-inelastic neutrinonucleus interactions [11] and high-energy cosmic-ray interactions in the atmosphere [12]. In these cases the nPDFs characterize the initial state before the collisions and, if known accurately, can lead to the discovery of new phenomena.…”

Nuclear structure functions at a future electron-ion collider

et al. 2017

The quantitative knowledge of heavy nuclei's partonic structure is currently limited to rather large values of momentum fraction x-robust experimental constraints below x ∼ 10 −2 at low resolution scale Q 2 are particularly scarce. This is in sharp contrast to the free proton's structure which has been probed in Deep Inelastic Scattering (DIS) measurements down to x ∼ 10 −5 at perturbative resolution scales. The construction of an electron-ion collider (EIC) with a possibility to operate with a wide variety of nuclei, will allow one to explore the low-x region in much greater detail. In the present paper we simulate the extraction of the nuclear structure functions from measurements of inclusive and charm reduced cross sections at an EIC. The potential constraints are studied by analyzing simulated data directly in a next-toleading order global fit of nuclear Parton Distribution Functions based on the recent EPPS16 analysis. A special emphasis is placed on studying the impact an EIC would have on extracting the nuclear gluon parton distribution function, the partonic component most prone to nonlinear effects at low Q 2 . In comparison to the current knowledge, we find that the gluon parton distribution function can be measured at an EIC with significantly reduced uncertainties.
