Query: Direct Fragmentation of Quarkonia Including Fermi Motion Using
  Light-cone Wave Function   We investigate the effect of Fermi motion on the direct fragmentation of the
$J/\psi$ and $\Upsilon$ states employing a light-cone wave function. Consistent
with such a wave function we set up the kinematics of a heavy quark fragmenting
into a quarkonia such that the Fermi motion of the constituents split into
longitudinal as well as transverse direction and thus calculate the
fragmentation functions for these states. In the framework of our
investigation, we estimate that the fragmentation probabilities of $J/\psi$ and
$\Upsilon$ may increase at least up to 14 percent when including this degree of
freedom.
