We study the radiative correction to -broadening of a fast quark
in a quark-gluon plasma beyond the
soft gluon approximation.
We find that the radiative processes can suppress considerably
This differs dramatically from previous calculations to logarithmic
accuracy in the soft gluon approximation, predicting
a considerable enhancement of -broadening.
