“…Various models and implementations have been proposed [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32] but since the size of the nuclear effects is large and there are discrepancies among models, it is important to provide experimental measurements that are as model-independent as possible. If the experimental signature is defined topologically by the particles leaving the target nucleus rather than the particles produced at the neutrino interaction vertex, the results can be compared with any specific model that combines the nucleon-level cross section, nuclear effects and final-state interactions.…”

We report the measurements of the single and double differential cross section of muon neutrino charged-current interactions on carbon with a single positively charged pion in the final state at the T2K offaxis near detector using 5.56 × 10 20 protons on target. The analysis uses data control samples for the background subtraction and the cross section signal, defined as a single negatively charged muon and a single positively charged pion exiting from the target nucleus, is extracted using an unfolding method. The model-dependent cross section, integrated over the T2K off-axis neutrino beam spectrum peaking at 0.6 GeV, is measured to be σ ¼ ð11.76 AE 0.44ðstatÞ AE 2.39ðsystÞÞ × 10 −40 cm 2 nucleon −1. Various differential cross sections are measured, including the first measurement of the Adler angles for single charged pion production in neutrino interactions with heavy nuclei target.

“…Weak single pion production off the nucleon has been extensively studied at intermediate energies with various phenomenological models. Models accounting for the ∆(1232) resonance and higher nucleon excitations have been developed [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20], with some studies specifically addressing the NC case [21,22]. In addition to nucleon excitation, most of these models incorporate non-resonant amplitudes with form factors in the vertices.…”

Neutral-current weak pion production off the nucleon in covariant chiral perturbation theory

Neutral current single pion production induced by neutrinos and antineutrinos on nucleon targets has been investigated in manifestly relativistic baryon chiral perturbation theory with explicit ∆(1232) degrees of freedom up to O(p 3 ). At low energies, where chiral perturbation theory is applicable, the total cross sections for the different reaction channels exhibit a sizable non-resonant contribution, which is not present in event generators of broad use in neutrino oscillation and cross section experiments such as GENIE and NuWro.

The charged current Cabibbo-supressed associated KΞ production off the nucleon induced by anti-neutrinos is studied at low and intermediate energies. The non-resonant terms are obtained using a microscopical model based on the SU(3) chiral Lagrangian. The basic parameters of the model are fπ, the pion decay constant, Cabibbo's angle, the proton and neutron magnetic moments and the axial vector coupling constants for the baryons octet, D and F, that are obtained from the analysis of the semileptonic decays of neutron and hyperons. In addition, we also consider Σ * (1385) resonance, which can decay in KΞ final state when this channel is open. The studied mechanism is the prime source of Ξ production at anti-neutrino energies around 2 GeV and the calculated cross sections at these energies can be measured at the current and future neutrino experiments. * rafi.alam.amu@gmail.com † ruizsig@ugr.es 1 |∆S| = 2 processes are highly suppressed.
