Possible bound state of the double heavy meson-baryon system

Abstract

We calculate the two-pion exchange potential between a heavy meson and a heavy baryon. We find this potential is as strong as the one-pion exchange potential between two heavy mesons and is enough to bind ΛbBˉ\Lambda_b-\bar B. Though our result is sensitive to the cut-off, the value of the cut-off is in the reasonable region.
