Finite-temperature spectral function of the vector mesons in an AdS/QCD model

Understand

We use the soft-wall AdS/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 AdS 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.
