Radiative energy loss of high energy quarks in finite-size nuclear matter and quark-gluon plasma
The induced gluon radiation of a high energy quark in a finite-size QCD medium is studied. For a sufficiently energetic quark produced inside a medium we find the radiative energy loss AEq oc L1, where L is the distance passed by quark in the medium. It has a weak dependence on the initial quark energy Eq. The L2 dependence turns to L] as the quark energy decreases. Numerical calculations are performed for a cold nuclear matter and a hot quark-gluon plasma. For a quark incident on a nucleus we predict AEq « 0AEq(L/\0 fm)^, with β close to unity.
