“…[29,32,36]. Last but not least, the current analysis includes the previously unknown m c -independent part of G (2) 78 [37], all the relevant BLM corrections to G (2) ij with i, j = 7 [31,38,39], tree-level contributions T (0) ij [23,24], four-body NLO corrections [24], as well as the updated non-perturbative corrections [14,40,41]. The only contributions to G (2) ij with i, j ∈ {1, 2, 7, 8} that remain neglected are the unknown (n ≥ 3)-body final state contributions to the non-BLM parts of G (2) ij with i, j = 7.…”
