Abstract

It has been argued that higher order 2→3 O(α_s³ QCD processes play an important role in the hadroproduction of heavy quarks. We propose forward-backward or charge conjugation asymmetry as a distinctive signature of the higher-order QCS production mechanism. We analyse the physical origin of the asymmetries and show that observed forward-backward asymmetries for the heavy quark or decay lepton are 5% or less for realistic experimental conditions. Observation of asymmetries in excess of our calculated values would signal the production of heavy quarks via unconventional mechanisms.
