Query: Gluon Emission of Heavy Quarks: Dead Cone Effect   The lowest-order induced soft gluon radiation processes of heavy quarks have
been analyzed to quantify the dead cone effect. This effect is most likely
expected to suppress significantly the energy loss of charm quarks passing an
amorphous color-neutral deconfined medium, as has been concluded from recent
experiments at RHIC.
