Heavy quark distribution function in hadrons

High Energy Physics - Phenomenology 2008-09-22 v1

Abstract

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 bb quark, one has to take into account terms of higher than (1/mc)2(1/m_c)^2 order for the cc quark.
