“…on the fluxes requires careful instrumentation of the beam line and data from dedicated Hadron production experiments such as MIPP [50] in the case of MINOS, HARP [51,52] for K2K and MiniBooNE, or NA61/SHINE [53] for T2K. For example, in MINOS the goal is to constrain Φ νµ at the 5% level using MIPP data.…”

Superbeam experiments can, in principle, achieve impressive sensitivities for CP violation in neutrino oscillations for large θ 13 . We study how those sensitivities depend on assumptions about systematical uncertainties. We focus on the second phase of T2K, the so-called T2HK experiment, and we explicitly include a near detector in the analysis. Our main result is that even an idealised near detector cannot remove the dependence on systematical uncertainties completely. Thus additional information is required. We identify certain combinations of uncertainties, which are the key to improve the sensitivity to CP violation, for example the ratio of electron to muon neutrino cross sections and efficiencies. For uncertainties on this ratio larger than 2%, T2HK is systematics dominated. We briefly discuss how our results apply to a possible two far detector configuration, called T2KK. We do not find a significant advantage with respect to the reduction of systematical errors for the measurement of CP violation for this setup.

“…Fig. 4 shows integrated π + and π − cross sections, measured by the HARP Collaboration [12] for different targets and different incident energies. We have to specify from the beginning that the experimental points correspond in fact to the integrated double differential cross sections over the acceptance of the experimental set-up.…”

“…Although this crude choice already gives reasonable results, we preferred to deform the uniform phase space distribution towards a slightly more aligned distribution on the direction of the collisions (in their center of mass). In order to test our ideas, we have performed a comparison of our results with the measurements of the HARP Collaboration [12]. This is actually the third motivation of this work, namely the comparison of our model predictions with an extensive and systematic set of data.…”

Extension of the Liège intranuclear cascade model at incident energies between 2 and 12 GeV. Aspects of pion production

The validity of the standard version of the Liège Intra-Nuclear Cascade (INCL4) model, which has been shown to be quite successful for the description of spallation reactions, is limited to an upper incident energy of ∼2 GeV, because inelastic elementary processes are restricted to the excitation and de-excitation of the Delta resonance. In this paper, the INCL4 model is extended to higher incident energy by including other inelastic elementary collisions. However, excitation of heavier baryonic resonances is replaced by direct multipion production in elementary nucleon-nucleon and pion-nucleon collisions. The predictions of the modified model for production of charged pions by proton and pion beams off nuclei are compared with experimental data of the HARP Collaboration for beam energies between 2 and 12 GeV. The apparent duality between the approach based on excitation of numerous baryonic resonances and our approach is briefly discussed.
