Imaginary potential of heavy quarkonia from AdS/QCD
The imaginary part of a heavy quarkonium potential is studied at finite temperature and chemical potential using a holographic AdS/QCD model with conformal invariance broken by a background dilaton. It is shown that the presence of the confining scale increases the absolute value of the imaginary po...

The imaginary part of a heavy quarkonium potential is studied at finite temperature and chemical potential using a holographic AdS/QCD model with conformal invariance broken by a background dilaton. It is shown that the presence of the confining scale increases the absolute value of the imaginary potential thus increasing the thermal width, reverse to the effect of the chemical potential. One step further, the results imply that the inclusion of the confining scale reduces the quarkonia dissociation while the chemical potential enhances it. |
