Abstract

In the framework of the one-boson exchange model, we have calculated the effective potentials between two heavy mesons BB^* and DD^* from the t- and u-channel \ensuremathπ-, \ensuremathη-, \ensuremathρ-, \ensuremathω-, and \ensuremathσ-meson exchanges with four kinds of quantum number: I=0, J^PC=1⁺⁺; I=0, J^PC=1^+\ensuremath-; I=1, J^PC=1⁺⁺; I=1, J^PC=1^+\ensuremath-. We keep the recoil corrections to the BB^* and DD^* systems up to O(\frac1M²). The spin-orbit force appears at O((1)/(M)), which turns out to be important for the very loosely bound molecular states. Our numerical results show that the momentum-related corrections are unfavorable to the formation of the molecular states in the I=0, J^PC=1⁺⁺ and I=1, J^PC=1^+\ensuremath- channels in the DD^* system.
