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 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 کاملSolar Neutrino Flux
We have measured the Coulomb dissociation of 8B into 7Be and proton at 254 MeV/nucleon using a large-acceptance focusing spectrometer. The astrophysical S17 factor for the 7Be(p,γ)8B reaction at Ec.m. = 0.25−2.78 MeV is deduced yielding S17(0) = 20.6± 1.2 (exp.) ± 1.0 (theo.) eV-b. This result agrees with the presently adopted zero-energy S17 factor obtained in directreaction measurements and w...
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 کاملThe diffuse supernova neutrino flux
I review the status and perspectives of the research on the diffuse flux of (core collapse) supernova neutrinos (DSNνF). In absence of a positive signal, several upper bounds exist in different detection channels. Of these, the strongest is the limit from SuperKamiokande (SK) of 1.2 electron antineutrinos cms at 90% confidence level above 19.3 MeV of neutrino energy. The predictions of the DSNν...
