Three-Point Functions at Finite Temperature

We study 3-point functions at finite temperature in the closed time path formalism. We give a general decomposition of the eight component tensor in terms of seven vertex functions. We derive a spectral representation for these seven functions in terms of two independent real spectral functions. We derive relationships between the seven functions and obtain a representation of the vertex tensor that greatly simplifies calculations in real time.Comment: 21 pages LaTeX; one ps-figure; Revised version, contains more references and discussio

Transverse momentum spectra and elliptic flow: Hydrodynamics with QCD-based equations of state

We present a family of equations of state within a quasiparticle model adjusted to lattice QCD and study the impact on azimuthal flow anisotropies and transverse momentum spectra within hydrodynamic simulations for heavy-ion collisions at energies relevant for LHC.Comment: Aug. 2007. 3 pp. Talk given at the Focus Week of the workshop Heavy Ion Collisions at the LHC - Last Call for Predictions, Genf, Switzerland, 29 May - 2 June 200
