Prompt atmospheric neutrino flux from the various QCD models

TL;DR

This paper evaluates the prompt atmospheric neutrino flux using various QCD models for heavy quark production, including nuclear corrections, and compares the results with experimental data from RHIC, LHC, and LHCb.

Contribution

It introduces a comprehensive evaluation of the prompt neutrino flux across different QCD models with nuclear corrections and compares predictions with experimental data.

Findings

Nuclear corrections reduce fluxes by 10-50% depending on the model.

Heavy quark production models show varying predictions for neutrino flux.

Comparison with experimental data helps constrain QCD models for heavy quark production.

Abstract

We evaluate the prompt atmospheric neutrino flux using the different QCD models for heavy quark production including the $b$ quark contribution. We include the nuclear correction and find it reduces the fluxes by $10 \% - 50\%$ according to the models. Our heavy quark results are compared with experimental data from RHIC, LHC and LHCb.
