On particle production for high energy neutrino beams

Abstract

Abstract. Analytical formulae for the calculation of secondary particle yields in p-A interactions are given. These formulae can be of great practical importance for fast calculations of neutrino fluxes and for designing new neutrino beam-lines. The formulae are based on a parameterization of the inclusive invariant cross sections for secondary particle production measured in p-Be interactions. Data collected in different energy ranges and kinematic regions are used. The accuracy of the fit to the data with the empirical formulae adopted is within the experimental uncertainties. Prescriptions to extrapolate this parameterization to finite targets and to targets of different materials are given. The results obtained are then used as an input for the simulation of neutrino beams. We show that our approach describes well the main characteristics of measured neutrino spectra at CERN. Thus it may be used in fast simulations aiming at the optimisation of the long-baseline neutrino beams at CERN and FNAL. In particular we will show our predictions for the CNGS beam from CERN to Gran Sasso.

Measurement of the neutrino-oxygen neutral-current interaction cross section by observing nuclear deexcitationγrays

“…Hadron production data from NA61/SHINE at CERN [18,19] is used to tune the simulation and evaluate the systematic error. The regions of phase space not covered by the NA61/SHINE data directly are tuned by extrapolating the data using the BMPT empirical parameterization [20]. Once particles leave the production target they are transported through the magnetic horns, target hall, decay volume, and beam dump using a GEANT3 [21] simulation with GCALOR [22] for hadronic interactions.…”

“…Fig. 7(b) as well as the range of predictions from several hadron production codes [25,[53][54][55]. For the points labeled ''Tuned MC'' the uncertainties are computed from the post-fit uncertainties on the functions A 0 , B 0 , and C 0 of Eq.…”

Measurement of the Muon Neutrino Inclusive Charged Current Cross Section on Iron using the MINOS Detector

“…These models simulate the interaction cascade of particles, thus accounting for reinteractions within long targets. However, simulations of interactions within the NuMI target using several of these models shows that they vary significantly in their predictions of meson production as shown in Alternatively, the data from hadron production experiments are parameterized analytically in terms of the phase space variables (p T and x F [58,59].…”
