Radiative Energy Loss of High Energy Quarks and Gluons in a Finite Volume Quark-gluon Plasma
The medium induced energy loss spectrum of a high energy quark or gluon traversing a hot QCD medium of finite volume is studied. We model the interaction by a simple picture of static scattering centres. The total induced energy loss is found to grow as L, where L is the extent of the medium. The solution of the energy loss problem is reduced to the solution of a Schrödingerlike equation whose ...
متن کاملDileptons from a Quark Gluon Plasma with Finite Baryon Density
We investigate the effects of a baryon-antibaryon asymmetry on the spectrum of dileptons radiating from a quark gluon plasma. We demonstrate the existence of a new set of processes in this regime. The dilepton production rate from the corresponding diagrams is shown to be as important as that obtained from the usual quark-antiquark annihilation. 25.70.Np, 12.38.Cy, 12.38.Mh Typeset using REVTEX 1
متن کاملPhase transition of a finite quark-gluon plasma
The deconfinement transition region between hadronic matter and quarkgluon plasma is studied for finite volumes. Assuming simple model equations of state and a first order phase transition, we find that fluctuations in finite volumes hinder a sharp separation between the two phases around the critical temperature, leading to a rounding of the phase transition. For reaction volumes expected in h...
متن کاملVolume Effect of Bound States in Quark Gluon Plasma
Bound states, such as qq and qq̄, may exist in the Quark Gluon Plasma. As the system is at high density, the volume of the bound states may evoke a reduction to the phase space. We introduce an extended bag model to investigate qualitatively the volume effect on the properties of the system. We find a limit temperature where the bound states start to be completely melted. PACS number(s): 12.38.M...
متن کاملQuark-Gluon Plasma Signatures
Aspects of quark-gluon plasma signatures that can be measured by CMS are discussed. First the initial conditions of the system from minijet production are introduced, including shadowing effects. Color screening of the Upsilon family is then presented, followed by energy loss effects on charm and bottom hadrons, high pT jets and global observables. ∗) This work was supported in part by the Dire...
