    Publicado 2000
    “…We argue that these differences may be exploited as indicators of the formation of a quark-gluon plasma in relativistic heavy-ion collisions, because fluctuations created in the initial state survive until freeze-out due to the rapid expansion of the hot fireball.…”

    Publicado 2000
    “…This is a summary of the latest results of the DELPHI collaboration on the properties of quark and identified gluon jets. It covers the measurement of the quark and gluon splitting kernels, the fragmentation functions of gluon and quark jets and their scaling violation behavior as well as an analysis of the scale dependence of the multiplicities of gluon and quark jets. …”
