Mesons Spectral Functions at Finite Temperature
We investigate the thermal spectral densities for (pseudo)scalar and vector currents in the framework of the real time formalism when mass of two quarks are different. Such spectral densities are necessary for the phenomenological investigation of in-medium properties of hadrons. We use the quark propagator at finite temperature and calculate annihilation and scattering parts of spectral densit...
متن کاملHolographic Model for Mesons at Finite Temperature
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 Nambu-Goldstone theorem for the chiral symmetry breaking and generalized Gell-Mann-Oakes-Renner relation are assured at finite temperature. Furthermore, we can s...
متن کاملMoving rho-mesons at finite temperature
An exciting aspect of hadron physics is the question how a hadron changes its properties once it is put in a strongly interacting environment. Here, the vector mesons deserve special attention as they couple directly to (virtual) photons. The latter can decay into dileptons which leave the strongly interacting system untouched. Via that process information about possible in-medium modifications...
متن کاملBottomonia correlators and spectral functions at zero and finite temperature
We present preliminary studies of bottomonia spectral functions at zero and finite temperature using quenched anisotropic lattices. The heavy quark is treated within Fermilab approach. We find no modification of the η b and ϒ states up to temperatures 2.3T c while our study suggest dissolution of χ b state at 1.15T c. c Copyright owned by the author(s) under the terms of the Creative Commons At...
متن کاملCharmonium correlators and spectral functions at finite temperature
We present an operational approach to address the in-medium behavior of charmonium and analyze the reliability of maximum entropy method (MEM). We study the dependences of the ratio of correlators to the reconstructed one and the free one on the resonance’s width and the continuum’s threshold. Furthermore, we discuss the issue of the default model dependence of the spectral function obtained fr...
