We study contribution of radiative processes to -broadening of fast partons in an expanding quark–gluon plasma. It is shown that the radiative correction to for the QGP produced in AA-collisions at RHIC and LHC may be negative, and comparable in absolute value with the non-radiative contribution. We have found that the QGP expansion enhances the radiative suppression of -broadening as compared to the static medium.
