Gluon exchange and the short-distance form of the hadron-antihadron potential

On the basis of gluon exchanges at short distances and the non-relativistic approximation for the motion of quarks inside hadrons, some plausibility arguments are given that the potential describing the interaction of hantih in the Schroedinger equation must vanish at small distances where the exchange of the usual mesons is no more applicable. Some consequences of such a potential for the existence of P-wave bound states of molecular charmonium are presented. (Auth.)
