Properties of quark gluon plasma from lattice calculations
I discuss lattice QCD calculations of the properties of strongly interacting matter at finite temperature, including the determination of the transition temperature Tc, equation of state, different static screening lengths and quarkonium spectral functions. The lattice data suggest that at temperatures above 2.0Tc many properties of the quark gluon plasma can be understood using weak coupling a...
متن کاملQuark-gluon plasma phenomenology from the lattice
The FASTSUM Collaboration has calculated several quantities relevant for QCD studies at non-zero temperature using the lattice technique. We report here our results for the (i) interquark potential in charmonium; (ii) bottomonium spectral functions; and (iii) electrical conductivity. All results were obtained with 2+1 flavours of dynamical fermions on an anisotropic lattice which allows greater...
متن کاملTransport properties of the quark-gluon plasma from lattice QCD
I review the progress made in extracting transport properties of the quark-gluon plasma from lattice QCD simulations. The information on shear and bulk viscosity, the “low-energy constants” of hydrodynamics, is encoded in the retarded correlators of Tμν, the energy-momentum tensor. Euclidean correlators, computable on the lattice, are related to the retarded correlators by an integral transform...
متن کاملThe quark gluon plasma: Lattice computations put to experimental test
I describe how lattice computations are being used to extract experimentally relevant features of the quark gluon plasma. I deal specifically with relaxation times, photon emissivity, strangeness yields, event-by-event fluctuations of conserved quantities and hydrodynamic flow. Finally I give evidence that the plasma is rather liquid-like in some ways.
متن کاملAnisotropic Lattice and Its Application to Quark Gluon Plasma
Similarly dZ(R)/dR is written by the I1 and I2[1],[2]. The path of the integration is a closed circle on the complex plane x. In principle its radius r is arbitrary, but numerical integration requires adequate radius. We apply Simpson method for the numerical integration, and search for the region of r and number of the divisionN where < U > is stable with the change of r and N . It is observed...
