The hyperfine splitting in QCD mesonic screening masses at asymptotically large temperatures

Abstract We determine the hyperfine splitting in the QCD flavour non-singlet mesonic screening masses at asymptotically large temperatures. The analytic calculation is carried out in the dimensionally-reduced effective theory where the first non-zero contribution is of O(g 4) in the QCD coupling con...
