Hadronization in Nuclear Matter
Nuclei are unique analyzers of the space-time development of jets at early stage. We argue that the gluon bremsstrahlung, rather than the color string, is the main mechanism of hadronization of highly virtual quarks produced in a hard interaction. It results in an energyand time-independent density of energy loss, like a color string, but steeply dependent on the quark virtuality. Effects of fo...
متن کاملSudden hadronization in relativistic nuclear collisions
We formulate and study a mechanical instability criterion for sudden hadronization of dense matter fireballs formed in 158A GeV Pb-Pb collisions. Considering properties of quark-gluon matter and hadron gas we obtain the phase boundary between these two phases and demonstrate that the required deep quark-gluon-plasma supercooling prior to sudden hadronization has occurred.
متن کاملHadronization in Nuclear Environment and Electroproduction of Leading Hadrons∗
Radiative energy loss of a highly virtual quark originating from a deep-inelastic electron scattering plays a crucial role in production of leading hadrons off nuclei. The density of energy loss for gluon radiation turns out to be timeand energy–dependent in inclusive hadron production. Important phenomena involved are Sudakov’s suppression of no radiation of that part of gluon spectrum, which ...
متن کاملHadronization in nuclear DIS and ultra-relativistic HIC
We present a transport theoretical analysis of hadron attenuation in deep inelastic lepton scattering (DIS) off complex nuclei in the kinematic regime of the HERMES experiment. The HERMES data indicate the presence of strong prehadronic final state interactions shortly after the elementary lepton-nucleon interaction. The contribution of such (pre-)hadronic final state interactions to the observ...
