Configuration entropy of Υ 1S state in strong coupling plasma

To better understand the effects of strong coupling and QCD at high temperature in QGP, by using holographic model, we investigate the dissociation effect of bottomonium under the higher-order curvature corrections to the supergravity action corresponding to the corrections of large N expansion of boundary CFT in the side of field theory. The results show that effective potential is not a good physical quantity to estimate the dissociation strength of bottomonium in the case of finite wave number and considering the higher-order curvature corrections. Therefore, we calculate the quasinormal spectra (QNMs) and the differential configuration entropy (DCE). It is found that the dissociation effect is stronger for the stronger coupling.

Automated summary

This paper investigates the dissociation effect of bottomonium using a holographic model that considers higher-order curvature corrections. The results show that the effective potential is not suitable for estimating the dissociation strength of bottomonium under finite wave numbers and higher-order curvature corrections. By calculating the quasinormal spectra and the differential configuration entropy, it is found that the dissociation effect becomes stronger with stronger coupling.
