AI 中文摘要
在这些论文中,我们总结了近期利用量子色动力学(QCD)中的超渐近展开来确定最轻胶球质量的进展。本文详细介绍了我们的方法,精确确定了主导重整化子归一化常数,并从两个独立物理系统中提取胶球质量,最终得到重整化群不变且方案无关的结果$\Lambda_{B}^{\rm PV} = 2.44(7) r_0^{-1}$。
英文摘要
In these proceedings, we provide a summary of our recent advancements in determining the mass of the lightest gluelump using hyperasymptotic expansions in Quantum Chromodynamics (QCD) \cite{Ayala2025}. This paper details our methodology, our precise determination of leading renormalon normalization constants, and our extraction of the gluelump mass from two independent physical systems, yielding a final combined, renormalization-group-invariant and scheme-independent result of $Λ_{B}^{\rm PV} = 2.44(7) r_0^{-1}$.
