“…The most general one assumes a full chain simulation of the neutrino beamline: an interaction of primary protons with the target, propagation of secondaries through the setup, reinteractions and finally production of neutrinos in the decay. For each MC event the interaction chain of hadrons is stored to be re-weighted later with experimentally measured cross sections [3] which, in turn, are obtained in ancillary hadron production experiments [2,4]. As a variation of this method the re-weighting of hadron multiplicities could be done at a surface of the target, which would take away a dependence of the results on an interaction model used for simulation inside the target [5].…”

A precise prediction of expected neutrino fluxes is required for a long-baseline accelerator neutrino experiment. The flux is used to measure neutrino cross sections at the near detector, while at the far detector it provides an estimate of the expected signal for the study of neutrino oscillations. In the talk several approaches to constrain the ν flux are presented. The first is the traditional one when an interaction chain for the neutrino parent hadrons is stored to be weighted later with real measurements. In this approach differential hadron cross sections are used which, in turn, are measured in ancillary hadron production experiments. The approach is certainly model dependent because it requires an extrapolation to different incident nucleon momenta assuming xF scaling as well as extrapolation between materials having different atomic numbers. In the second approach one uses a hadron production yields off a real target exploited in the neutrino beamline. Yields of neutrino parent hadrons are parametrized at the surface of the target, thus one avoids to trace the particle interaction history inside the target. As in the case of the first approach, a dedicated ancillary experiment is mandatory. Recent results from the hadron production experiments -NA61/SHINE at CERN (measurements for T2K) and MIPP at Fermilab (measurements for NuMI) -are reviewed.

In this research paper, the comprehensive results on the double differential yield of [Formula: see text] and [Formula: see text] mesons, protons and antiprotons as a function of laboratory momentum are reported. These hadrons are produced in proton–carbon interaction at 60 GeV/c. EPOS 1.99, EPOS-LHC and QGSJETII-04 models are used to perform simulations. Comparing the predictions of these models show that QGSJETII-04 model predicts higher yields of all the hadrons in most of the cases at the peak of the distribution. In this interval, the EPOS 1.99 and EPOS-LHC produce similar results. In most of the cases at higher momentum of the hadrons, all the three models are in good agreement. For protons, all models are in good agreement. EPOS-LHC gives high yield of antiprotons at high momentum values as compared to the other two models. EPOS-LHC gives higher prediction at the peak value for [Formula: see text] mesons and protons at higher polar angle intervals of [Formula: see text] and [Formula: see text], respectively, and EPOS 1.99 gives higher prediction at the peak value for [Formula: see text] mesons for [Formula: see text]. The model predictions, except for antiprotons, are compared with the data obtained by the NA61/SHINE experiment at 31 GeV/c proton–carbon collision, which clearly shows that the behavior of the distributions in models are similar to the ones from the data but the yield in data is low because of lower beam energy.
