Quark-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...
متن کاملDeconfinement and Quark – Gluon Plasma
The theory of confinement and deconfinement is discussed as based on the properties of the QCD vacuum. The latter are described by field correlators of colour-electric and colour-magnetic fields in the vacuum, which can be calculated analytically and on the lattice. As a result one obtains a self-consistent theory of the confined region in the (µ, T) plane with realistic hadron properties. At t...
متن کاملQuark-gluon Plasma Thermalization and Plasma Instabilities
Here is a basic question: What is the (local) thermalization time for quarkgluon plasmas (QGPs) in heavy ion collisions? That’s a difficult question, so let’s ask a simpler one: What is it for arbitrarily high energy collisions, where the running coupling constant is small, αs ≪ 1? Even that turns out to be complicated, so let me focus on an even simpler version, first posed by Baier, Mueller, ...
متن کاملTowards the Quark-Gluon Plasma
We discuss recent experimental results in the field of ultra-relativistic nuclear collisions. The emerging “picture” is a collectively expanding, initially hot and dense fireball in which strangenessand low-mass di-lepton pair production are enhanced and J/Ψ production is suppressed compared to expectations from nucleon-nucleon collisions. It is argued that, taken together, these data provide c...
متن کاملsignal the quark gluon plasma ?
We first review the production and the possible chemical equilibration of strange particles at CERN-SPS energies within a microscopic hadronic transport calculation. It is shown in particular that the strange quarks are produced initially via string excitations in the primary, secondary and ternary interactions. We then further elaborate on a recent idea of antihyperon production by multi-meson...
