Research output: Contribution to journalArticlepeer-review


Characterizing the energy loss of partons in nuclear matter became a matter of considerable theoretical and phenomenological interest over the past few years. In spite of this activity there is no agreed to value for partonic dE/dx(GeV/fm) in either cold or hot nuclear matter, though there is general agreement that the rate of energy loss in the latter exceeds that of the former. Though, much of the problem stems from the inability to directly measure this energy loss, and the lack of a common agreement of the processes and mechanisms to be included in specifying the energy loss. This paper briefly presents the current status of the problem, present a clear idea of quark energy loss in the nuclear medium, and delineate an experimental program capable of determining the parameters to adequately characterize quark energy loss in cold nuclei.
