Query: Impact of the inelastic proton -- nucleus cross section on the prompt
  neutrino flux   The description of the inelastic proton -- nucleus cross section at very high
energies is still an open question. The current theoretical uncertainty has
direct impact on the predictions of the cosmic ray and neutrino physics
observables. In this paper we consider different models for the treatment of
$\sigma_{inel}^{pA}$, compare its predictions at ultrahigh cosmic ray energies
and estimate the prompt neutrino flux at the neutrino energies that have been
probed by the IceCube Observatory. We demonstrate that depending of the model
used to describe $\sigma_{inel}^{pA}$, the predictions for the prompt neutrino
flux can differ by a factor of order of three. Such result demonstrate the
importance of a precise measurement of the inelastic proton -- nucleus cross
section at high energies.
