| Abstract | Miklos Gyulassy1 and Michael Pliimer2 Nuclear Science Division Lawrence Berkeley Laboratory Berkeley, CA 94 720 USA LBL-27885 The sensitivity of nuclear attenuation in 10-100 GeV lepton nucleus (.eA) reactions to space-time aspects of hadronization is investigated within the context of the Lund string model. We consider two mechanisms for attenuation in a nucleus: (1) final state cascading and (2) string flip excitations. Implications for the evolution of the energy density in nuclear collisions are discussed. 1 The Formation Length in String Models A successful string phenomenology of hadronic multi particle production in e+ e-, pp, pA and AA collisions has been developed by the Lund[1,2] and Saclay[3] groups. The relativistic space-time picture of hadronization implied by such models however has not yet been adequately tested. Deep inelastic lepton nucleus (.eA) reactions provide an ideal testing ground for string dynamics because the initial string configuration is under direct experimental control and only one string is excited. We therefore apply the basic concepts of these models (concerning string excitation, scattering and fragmentation) as well as the available Monte Carlo routines [4,5] as the input for our analysis of nuclear effects on distributions of secondaries in such reactions. This report is condensed from ref. [6], where more details and discussion can be found. A string is specified by its light cone momenta E± = E ± Pz, its transverse momentum P .L and the quark flavors at the ends. We neglect here possible kinks corresponding to gluon jets. While the string models used in phenomenological applications do not contain any configuration space description of either string * Talk presented at Rio de Janeiro Int.
