Radiative p⊥-broadening of fast partons in an expanding quark-gluon plasma
Abstract
We study contribution of radiative processes to p⊥-broadening of fast partons in an expanding quark-gluon plasma. It is shown that the radiative correction to ⟨p⊥2⟩ 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 p⊥-broadening as compared to the static medium.
