Charmonium ground and excited states at finite temperature from complex Borel sum rules
Charmonium spectral functions in vector and pseudoscalar channels at finite temperature are investigated through the complex Borel sum rules and the maximum entropy method. Our approach enables us to extract the peaks corresponding to the excited charmonia, ψ′ and ηc′, as well as those of the ground...
