“…Such additional processes not only contribute to the measured total cross section but also can affect the neutrino energy reconstruction. These new models have had success in describing MiniBooNE CCQE data [13][14][15][16][17] and T2K CC data [18][19][20][21][22]. However, models that simultaneously describe all data sets from low and high energy experiments remain elusive [17,[20][21][22][23].…”

This paper reports a measurement by the T2K experiment of the ν μ charged current quasielastic (CCQE) cross section on a carbon target with the off-axis detector based on the observed distribution of muon momentum (p μ ) and angle with respect to the incident neutrino beam (θ μ ). The flux-integrated CCQE cross section was measured to be hσi ¼ ð0.83 AE 0.12Þ × 10 −38 cm 2 . The energy dependence of the CCQE cross section is also reported. The axial mass, M QE A , of the dipole axial form factor was extracted assuming the Smith-Moniz CCQE model with a relativistic Fermi gas nuclear model. Using the absolute (shape-only) p μ -cos θ μ distribution, the effective M

“…The MiniBooNE and MINERvA results show also significant normalization and shape discrepancies between each other [3], and currently no theoretical model can explain all the pion production data available. Additional pion production data can help to constrain the pion production models and give valuable information on the nucleon-Δ axial form factor [6,7].…”

The T2K off-axis near detector, ND280, is used to make the first differential cross section measurements of muon neutrino charged current single positive pion production on a water target at energies ∼0.8 GeV.The differential measurements are presented as a function of the muon and pion kinematics, in the restricted phase space defined by p π þ > 200 MeV=c, p μ > 200 MeV=c, cosðθ π þ Þ > 0.3 and cosðθ μ Þ > 0.3. The total flux integrated ν μ charged current single positive pion production cross section on water in the restricted phase space is measured to be hσi ϕ ¼ 4.25 AE 0.48ðstatÞ AE 1.56ðsystÞ × 10 −40 cm 2 =nucleon. The total cross section is consistent with the NEUT prediction (5.03 × 10 −40 cm 2 =nucleon) and 2σ lower than the GENIE prediction (7.68 × 10 −40 cm 2 =nucleon). The differential cross sections are in good agreement with the NEUT generator. The GENIE simulation reproduces well the shapes of the distributions, but overestimates the overall cross section normalization.

“…The role of theoretical calculations is crucial for these analysis; they have first suggested the importance of multinucleon emission in quasielastic and inclusive neutrino-nucleus cross sections [10][11][12][13], including in the dynamics various nuclear effects such as meson-exchange currents (MEC) with and without ∆-isobar excitations, final-state interactions (FSI), shortrange correlations (SRC), the random-phase approximation (RPA), effective interactions, etc. These ingredients lead to discrepancies between the theoretical predictions, and these need to be clarified in order to reduce the systematic uncertainties in neutrino data analyses [14][15][16][17].…”

Angular distribution in two-particle emission induced by neutrinos and electrons

et al. 2014

The angular distribution of the phase space arising in two-particle emission reactions induced by electrons and neutrinos is computed in the laboratory (Lab) system by boosting the isotropic distribution in the center of mass (CM) system used in Monte Carlo generators. The Lab distribution has a singularity for some angular values, coming from the Jacobian of the angular transformation between CM and Lab systems. We recover the formula we obtained in a previous calculation for the Lab angular distribution. This is in accordance with the Monte Carlo method used to generate twoparticle events for neutrino scattering [1]. Inversely, by performing the transformation to the CM system, it can be shown that the phase-space function, which is proportional to the two particle-two hole (2p-2h) hadronic tensor for a constant current operator, can be computed analytically in the frozen nucleon approximation, if Pauli blocking is absent. The results in the CM frame confirm our previous work done using an alternative approach in the Lab frame. The possibilities of using this method to compute the hadronic tensor by a boost to the CM system are analyzed.
