Abstract

The jet quenching parameter \stackrel\ifmmode \else \\fiq is analyzed for a quark jet propagating in an anisotropic plasma. The momentum anisotropy is calculated at high temperature of the underlying quark-gluon plasma. \stackrel\ifmmode \else \\fiq is explicitly estimated in leading-logarithmic approximation by the broadening of the massless quark interacting via gluon exchange. A plasma instability is present. Strong indications are found that \stackrel\ifmmode \else \\fiq is increasing with increasing anisotropy. Possible implications for the saturation scale Q_s in A\text\ensuremath-A collisions are pointed out.
