“…In particular, the simulation of calorimeter response and secondary interactions in tracking systems needs to be supported by experimental hadron production data. The results on forward production of charged pions by incident protons are the subject of previous HARP publications [14][15][16][17][18]. The analysis of the results on charged pion production with charged pion beams on the full range of targets can be found in Ref.…”

“…All relevant physics processes are considered, including multiple scattering, energy loss, absorption, and re-interactions. The track reconstruction used in this analysis and the simulation are identical to the 045208-20 ones used for the π + production in p-Be collisions [15]. A detailed description of the corrections and their magnitude can be found there.…”

Measurements of the double-differential proton production cross-section d 2 σ /dpd in the range of momentum 0.5 GeV/c p < 8.0 GeV/c and angle 0.05 rad θ < 0.25 rad in collisions of charged pions and protons on beryllium, carbon, aluminium, copper, tin, tantalum, and lead are presented. The data were taken with the large acceptance HARP detector in the T9 beam line of the CERN Proton Synchrotron. Incident particles were identified by an elaborate system of beam detectors and impinged on a target of 5% of a nuclear interaction length. The tracking and identification of the produced particles was performed using the forward spectrometer of the HARP experiment. Results are obtained for the double-differential cross-sections mainly at four incident beam momenta (3,5,8, and 12 GeV/c). Measurements are compared with predictions of the GEANT4 and MARS Monte Carlo generators.

“…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.
