Uncertainty estimates for atmospheric neutrino fluxes
Proceedings of the 30th International Cosmic Ray Conference, ICRC 2007 5:HE PART 2 (2007) 1495-1498
Abstract:
Starting from a survey of experimental measurements, we assign uncertainties to the two most critical inputs to the calculation of fluxes of unoscillated atmospheric neutrinos, the hadron production and the primary cosmic ray fluxes. We then propagate these uncertainties through the entire flux calculation to arrive at estimates of the uncertainties in the fluxes of neutrinos and of various ratios of neutrino fluxes. We find that there is indeed a significant cancellation of flux uncertainties when these ratios are made. The uncertainties as a function of neutrino energy will be presented.Hadron interaction simulation in atmospheric neutrino flux calculations

Abstract:
The aspects of hadron simulation affecting the calculation of unoscillated atmospheric neutrino fluxes is discussed. The method of simulating the atmospheric cascades is described. An evaluation of the errors on the atmospheric neutrino fluxes and various experimentally convenient ratios is presented. A new measurement of hadron production with the NA49 experiment at CERN is briefly reported.Measurement of the ratio Γ(KL → π+π-)/Γ(KL → π±e∓ν) and extraction of the CP violation parameter |η+-|
