An Application of Diagrammatic Renormalization to $2^{++}$ Tensor Di-Gluonium

T. de Oliveira, Siyuan Li, T. G. Steele

We apply the diagrammatic renormalization method to the NLO analysis of the $2^{++}$ tensor di-gluonium channel within the QCD sum-rules approach. Diagrammatic renormalization elim…
