Measuring hadron properties at finite temperature.
We estimate the numbers and mass spectra of observed lepton and kaon pairs produced from φ meson decays in the central rapidity region of an Au+Au collision at lab energy 11.6 GeV/nucleon. The following effects are considered: possible mass shifts, thermal broadening due to collisions with hadronic resonances, and superheating of the resonance gas. Changes in the dilepton mass spectrum may be s...
متن کاملCalculation of Thermodynamic Properties of the Quasi-one Dimensional Liquid 3He at Finite Temperature
We have used a variational approach to calculate some thermodynamic properties of the quasi-one dimensional liquid 3He such as the energy, entropy, free energy, equation of state and heat capacity at finite temperature. We have employed the Lennard-Jones potential as the inter-atomic interaction. We have seen that the total energy increases by increasing both temperature and density....
متن کاملProperties of vector mesons at finite temperature: Effective Lagrangian approach.
The properties of ρ-mesons at finite temperature (T ) are examined with an effective chiral lagrangian in which vector and axial-vector mesons are included as massive Yang-Mills fields of the chiral symmetry. It is shown that, at T 2 order, the effective mass is not changed but only the mixing effect in vector and axial-vector correlator appears. PACS numbers : 25.75+r, 11.10.Wx, 11.30.Rd Types...
متن کاملCharmonium properties at finite temperature on quenched anisotropic lattices
We study charmonium properties below and above Tc up to 1.8Tc, on quenched anisotropic lattices. Information of the spectral functions is extracted using the maximum entropy method and the constrained curve fitting. We also calculate the color singlet and averaged free energies and evaluate the charmonium spectrum with the potential model analysis. The relation between the lattice result of the...
متن کاملMagnetic properties of confined bosonic vacuum at finite temperature
We compute the combined effect of confinement, an external magnetic field and temperature on the vacuum of the charged scalar field using Schwinger’s formula for the effective action in the imaginary time formalism. The final result reproduces an effective Lagrangian similar to the Heisenberg-Euler one in the limit of no confinement, in the case of confinement it provides the necessary correcti...
