Intrinsic charm contribution to the prompt atmospheric neutrino flux

Understand

In this work we investigate the impact of intrinsic charm on the prompt atmospheric neutrino flux.

• The color dipole approach to heavy quark production is generalized to include the contribution of processes initiated by charm quarks.
• The prompt neutrino flux is calculated assuming the presence of intrinsic charm in the wave function of the projetile hadron.
• The predictions are compared with previous color dipole results which were obtained taking into account only the process initiated by gluons.
