Abstract:
The induced momentum spectrum of soft gluons radiated from a high energy quark propagating through a QCD medium is derived in the BDMPS formalism. A calorimetric measurement for the medium dependent energy lost by a jet with opening angle is proposed.The fraction of this energy loss with respect to the integrated one appears to be the relevant observable.It exhibits a universal behaviour in terms of the variable where is the size of the medium and the transport coefficient. Phenomenological implications for the differences between cold and hot QCD matter are discussed.- quantum chromodynamics: matter
