====== TTP98-31 Charge Asymmetry of Heavy Quarks at Hadron Colliders ======
 
 
<hidden TTP98-31  Charge Asymmetry of Heavy Quarks at Hadron Colliders > A sizeable difference in the differential production cross section
 of top and antitop quarks, respectively, is predicted for
 hadronically produced heavy quarks.
 It is of order $\alpha_s$ and arises from the
 interference between charge odd and even amplitudes respectively.
 For the TEVATRON it amounts up to 15\% for the differential
 distribution in suitable chosen kinematical regions.
 The resulting integrated forward-backward asymmetry of
 4--5\% could be measured in the next round of experiments.
 At the LHC the asymmetry can be studied by selecting
 appropriately chosen kinematical regions.
 Furthermore, a slight preference at LHC for centrally
 produced antitop is predicted, with top quarks more abundant at
 large positive and negative rapidities.
