The moments of the heavy quark-parton distribution functions in a heavy pseudoscalar meson, obtained in QCD sum rules, are expanded in the inverse heavy quark. Comparison with the finite mass results reveals that while the heavy mass expansion works reasonably well for the b quark, one has to take into account terms of higher than (1/mc) 2 order for the c quark. In this talk I will very shortly report the result, obtained recently in my paper [1]. The problem is that there exist a large number… CONTINUE READING
