Tau Neutrino Fluxes from Atmospheric Charm
We present an evaluation of the atmospheric tau neutrino flux in the energy range between 102 and 106 GeV. The main source of tau neutrinos is from charmed particle production and decay. The ντN → τX event rate for a detector with a water equivalent volume of 1 km3 is on the order of 60-100 events per year for Eτ > 100 GeV, reducing to 18 events above 1 TeV. Event rates for atmospheric muon neu...
متن کاملCharm Production and High Energy Atmospheric Muon and Neutrino Fluxes
Production of muons and neutrinos in cosmic ray interactions with the atmosphere has been investigated with Monte Carlo models for hadronic interactions. The resulting conventional muon and neutrino fluxes (from π and K decays) agree well with earlier calculations, whereas our prompt fluxes from charm decays are significantly lower than earlier estimates. Charm production is mainly considered a...
متن کاملLepton fluxes from atmospheric charm revisited
We update predictions for lepton fluxes from the hadroproduction of charm quarks in the scattering of primary cosmic rays with the Earth’s atmosphere. The calculation of charm-pair hadroproduction applies the latest results from perturbative QCD through next-to-next-to-leading order and modern parton distributions, together with estimates on various sources of uncertainties. Our predictions for...
متن کاملDetermination of the Atmospheric Neutrino Fluxes from Atmospheric Neutrino Data
The precise knowledge of the atmospheric neutrino fluxes is a key ingredient in the interpretation of the results from any atmospheric neutrino experiment. In the standard data analysis, these fluxes are theoretical inputs obtained from sophisticated numerical calculations based on the convolution of the primary cosmic ray spectrum with the expected yield of neutrinos per incident cosmic ray. I...
