Resum
We use a nonperturbative QCD approach, the quark-gluon string model, to compute the
τ
-neutrino fluxes produced by fixed target
pA
collisions (where
A
is a target material) for incident protons of energies ranging from 120 to 800 GeV. The purpose of this calculation is to estimate in a consistent way the prompt background for the
