论文摘要
我们给出了plaquette的高氧化膨胀，其精度包括与领先的肾上腺素相关的终端。还考虑了转向效应。使用其Borel积分的主要价值处方来调节扰动系列。我们使用此分析来确定SU（3）纯Gluodynemics中Gluon冷凝物的确定，该纯Gluodynemics与用于耦合常数的规模和重新归一化方案无关：$ \ langle g^2 \ rangle _ {\ rm pv}（\ rm pv}（n_f = 0）= 0）= 3.15（18）\; R_0^{ - 4} $。
We give the hyperasymptotic expansion of the plaquette with a precision that includes the terminant associated to the leading renormalon. Subleading effects are also considered. The perturbative series is regulated using the principal value prescription for its Borel integral. We use this analysis to give a determination of the gluon condensate in SU(3) pure gluodynamics that is independent of the scale and renormalization scheme used for the coupling constant: $\langle G^2 \rangle_{\rm PV} (n_f=0)=3.15(18)\; r_0^{-4}$.
