DOI: 10.1007/jhep09(2020)016
Abstract: Abstract We give the hyperasymptotic expansion of the energy of a static quark-antiquark pair with a precision that includes the effects of the subleading renormalon. The terminants associated to the first and second renormalon are… read more here.

DOI: 10.1007/s00601-019-1531-y
Abstract: Trigonometric Rosen–Morse potential is suggested as a quark–antiquark interaction potential for studying thermodynamic properties and masses of heavy and heavy–light mesons. For this purpose, the N-radial Schrodinger equation is analytically solved using an exact-analytical iteration… read more here.

DOI: 10.1093/ptep/ptaa180
Abstract: Thermal systems have traditionally been modeled via Euclideanized space by analytical continuation of time to an imaginary time. We extend the concept to static thermal gradients by recasting the temperature variation as a variation in… read more here.

DOI: 10.1103/physrevd.103.034010
Abstract: We study the transitions between the different color states of a static quark-antiquark pair, singlet and octet, in a thermal medium. This is done nonperturbatively exploiting the infinite mass limit of QCD. This study is… read more here.
