Prompt atmospheric neutrinos and muons: Dependence on the gluon distribution function
Prompt atmospheric neutrinos and muons: Dependence on the gluon distribution function
We compute the next-to-leading order QCD predictions for the vertical flux of atmospheric muons and neutrinos from decays of charmed particles, for different PDF's (MRS-R1, MRS-R2, CTEQ-4M and MRST) and different extrapolations of these at a small partonic momentum fraction x. We find that the predicted fluxes vary up to …
