| contents | Elastic Energy Loss in an Expanding QGP L. F. Mackedanz M. B. Gay Ducati V. P. Gonçalves Física, Astronomía y Matemáticas Quark Gluon Plasma Elastic energy loss Running coupling constant The discovery of the jet quenching in central Au + Au collisions at the Relativistic Heavy-ion Collider (RHIC)has provided clear evidence for the formation of strongly interacting dense matter. It has been predicted to occurdue to the energy loss of high energy partons that propagate through the quark gluon plasma. Since the mediumis not static and it cools while expands, the strong coupling is not fixed, running with the evolution of thesystem. In this work, we present an investigation of the dependence on the value of the strong coupling inthe parton energy loss due to elastic scatterings in a parton plasma. We analyze different prescriptions for theQCD coupling and calculate the energy and length dependence of the fractional energy loss. Moreover, thequenching factor for light and heavy quarks is estimated. We found that the predicted enhancement of heavy tolight hadrons (D=p) ratio is strongly dependent on the running of the QCD coupling constant. 2007 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46437434 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.2B Vol.37 |
