  • A holographic model of QCD at finite temperature is proposed and thermal properties for light mesons are examined in terms of this model. We find interesting temperature dependences of masses and decay constants for several mesons, and the Nambu-Goldstone theorem for the chiral symmetry breaking and the generalized Gell-Mann-Oakes-Renner relation are assured at finite temperature. In the chiral limit, the speed of a pion in the thermal medium is found to decrease as temperature increases to the critical temperature of quark confinement-deconfinement transition.
  • We revisit the calculation of a heavy-quark potential in N=4 supersymmetric Yang-Mills theory at finite temperature using the AdS/CFT correspondence. As is widely known, the potential calculated in the pioneering works of Rey et al.[Nucl. Phys. B527, 171 (1998)] and Brandhuber et al.[Phys. Lett. B 434, 36 (1998)] is zero for separation distances r between the quark and the antiquark above a certain critical separation, at which the potential has a kink. We point out that by analytically continuing the string configurations into the complex plane, and using a slightly different renormalization subtraction, one obtains a smooth nonzero (negative definite)more » potential without a kink. The obtained potential also has a nonzero imaginary (absorptive) part for separations r>r{sub c}=0.870/{pi}T. Most importantly, at large separations r the real part of the potential does not exhibit the exponential Debye falloff expected from perturbation theory and instead falls off as a power law, proportional to 1/r{sup 4} for r>r{sub 0}=2.702/{pi}T.« less
  • We use the soft-wall anti-de Sitter/QCD model to investigate the finite-temperature effects on the spectral function in the vector channel. The dissociation of the vector meson tower onto the anti-de Sitter black hole leads to the in-medium mass shift and the width broadening in a way similar to the lattice QCD results for the heavy quarkonium at finite temperature. We also show the momentum dependence of the spectral function and find it consistent with screening in a hot wind.
  • We study scalar glueballs and scalar mesons at T{ne}0 in the soft wall holographic QCD model. We find that, using the anti-de Sitter-black-hole metric for all values of the temperature, the masses of the hadronic states decrease and the widths become broader when T increases, and there are temperatures for which the states disappear from the scalar glueball and scalar meson spectral functions. However, the values of the temperatures in correspondence of which such phenomena occur are low, of the order of 40-60 MeV. A consistent holographic description of in-medium effects on hadron properties should include the Hawking-Page transition, whichmore » separates the phase with the anti-de Sitter metric at small temperatures from the phase with anti-de Sitter-black-hole metric at high temperatures.« less
  • The properties of scalar mesons and glueballs at finite temperature are analyzed through a bottom-up holographic approach. We focus on the spectral functions and mass spectra. A discussion on hadron dissociation and deconfinement phase transition is also put forward.
