Revisiting glueball wave functions at zero and finite temperature
We study the sizes and thermal properties of glueballs in a three-dimensional compact Abelian gauge model on improved lattice. We predict the radii of ∼ 0.60 and ∼ 1.12 in the units of string tension, or ∼ 0.28 and ∼ 0.52 fm, for the scalar and tensor glueballs, respectively. We perform a well controlled extrapolation of the radii to the continuum limit and observe that our results agree with t...
متن کاملMeasuring 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 کاملThe Thermal Glueball at Finite Temperature in Su(3) Anisotropic Lattice Qcd∗
The thermal glueball is studied at finite temperature by using SU(3) anisotropic lattice QCD with βlat = 6.25, the renormalized anisotropy ξ ≡ as/at = 4 over the lattice of the size 20 × Nt with various Nt at the quenched level. While the narrow peak ansatz leads to the significant polemass reduction of about 300 MeV near the critical temperature Tc, Breit-Wigner ansatz which can take into acco...
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...
