The FLUKA atmospheric neutrino flux calculation
The 3–dimensional (3–D) calculation of the atmospheric neutrino flux by means of the FLUKA Monte Carlo model is here described in all details, starting from the latest data on primary cosmic ray spectra. The importance of a 3–D calculation and of its consequences have been already debated in a previous paper. Here instead the focus is on the absolute flux. We stress the relevant aspects of the ...
متن کاملFLUKA atmospheric neutrino flux
The atmospheric neutrino flux calculated with FLUKA was originally limited to 100÷200 GeV for statistical reasons. In order to make it available for the analysis of high energy events, like upward through-going muons detected by ν telescopes, we have extended the calculation so to provide a reliable neutrino yield per primary nucleon up to about 10 GeV/nucleon, as far as the interaction model i...
متن کاملProgresses in the validation of the FLUKA atmospheric ν flux calculation
The FLUKA calculation of the atmospheric neutrino fluxes have been cross–checked by comparing predictions on lepton fluxes in atmosphere to experimental data. The dependence of predicted neutrino fluxes on the shape and normalization of primary spectrum is also investigated.
متن کاملA 3–Dimensional Calculation of Atmospheric Neutrino Flux
An extensive 3-dimensional Monte Carlo calculation of the atmospheric neutrino flux is in progress with the FLUKA Monte Carlo code. The results are compared to those obtained under the 1-dimensional approximation, where secondary particles and decay products are assumed to be collinear to the primary cosmic ray, as usually done in most of the already existing flux calculations. It is shown that...
متن کاملUncertainties on Atmospheric Neutrino Flux Calculations
The strong evidence of new physics coming from atmospheric neutrino experiments has motivated a series of critical studies to test the robustness of the available flux calculations. In view of a more precise determination of the parameters of new physics, new and more refined flux calculations are in progress. Here we review the most important sources of theoretical uncertainties which affect t...
