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.

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.

DOI: 10.1103/physrevd.99.014506
Abstract: We consider the four point connected correlator representing a static quark-antiquark pair separated by a spatial distance R, propagating for a Euclidean time T. This function is computed by lattice Monte Carlo in SU(2) pure… read more here.
