Heavy-quarkonium interaction and the temperature dependence of the QCD static potential

摘要

We explore the temperature dependence of the heavy-quarkonium interaction based on the Bhanot -Peskin leading order perturbative QCD analysis. The Wilson coefficients are computed solving the Schr?dinger equation in a screened Coulomb heavy-quark potential. The inverse Mellin transform of the Wilson coefficients then allows for the computation of the 1S and 2S heavy-quarkonium gluon and pion total cross section at finite screening.
