Radiative quark $p_\perp$-broadening in a quark-gluon plasma at RHIC and LHC energies

We study the radiative correction to p⊥-broadening of a fast quark in a quark-gluon plasma beyond the soft gluon approximation. We find that the radiative contribution to quark p 2 ⊥ for RHIC and LHC conditions is negative.We study the radiative correction to $p_\perp$-broadening of a fast quark in a quark-gluon plasma beyond the soft gluon approximation. We find that the radiative contribution to quark $\langle p_\perp^2\rangle$ for RHIC and LHC conditions is negative
