A new correlation method to identify and separate charm and bottom production processes at RHIC | | Andre Mischke
; | | Date: |
8 Jul 2008 | | Abstract: | Electrons from semileptonic decays of heavy-flavor mesons (D and B) allows to
study the energy loss of heavy-quarks in nuclear collisions at sqrt(s) = 200
GeV at RHIC. Since theoretical calculations implying pQCD have shown that the
crossing point where bottom decay electrons starts to dominate over charm decay
electrons is largely unknown, an urgent need arise to access the relative
contributions independently. A correlation method is proposed to identify and
separate charm and bottom production processes on a statistical basis through
tagging of their decay electrons and open charmed mesons. The feasibility for
this method is shown using PYTHIA and MC@NLO simulations which also allow to
estimate the complete NLO contributions (including gluon-splitting diagrams). | | Source: | arXiv, 0807.1309 | | Services: | Forum | Review | PDF | Favorites | |
