Heavy quarks production in hadronic processes: qualitative study of higher-order Fock states. (English) Zbl 1182.81064
Summary: The contribution of the two particles Fock states for the production of a heavy quark in proton-pion and photon-pion collisions is studied. It is shown that the effect depends strongly on the produced heavy quark mass, and the choice of the factorization scale.
