It has been recently found that the heavy quark-antiquark QQbar pairmultiplicity, in certain phase space region (QQbar at short distance, soft andwith small velocity), satisfies an evolution equation formally similar to theBFKL equation for the high energy scattering amplitude. We find the exactsolution of the QQbar-equation and discuss the differences with the BFKLscattering amplitude.Comment: 18 pages, 3 figures, using JHEP3.cls Corrected typo
