使用运行的Quark质量重质化方案，以近来的Quark对生产的单差横截面预测以近后的顺序提出。在MSR方案$ M _ {\ MATHRM {t}}}^{\ textrm {\ textrm {msr}}（μ）$下，用于重级级别的尺度$μ$，在$ \ overline {\ textrm {ms {ms {ms {ms {ms {ms $ \ OVILLINE {M} _ {\ MATHRM {t}}（\ OVERLINE {M} _ {\ MATHRM {t}}）$，以及在$ \ overline {\ overline {\ textrm {ms}} $ conce $ conece $ \ yline {m oferline {m} $ scaleEs {m} $ scales {m math} = a}} =} {特别是，实施质量重新归一化量表与量子染色体动力学中的强耦合重归化量表和分解量表无关，可以研究独立的动力学量表变化。此外，提出了从实验数据中对顶部夸克MSR质量提取的第一个一致的一致提取。
Single-differential cross section predictions for top quark pair production are presented at next-to-leading order, using running top quark mass renormalization schemes. The evolution of the mass of the top quark is performed in the MSR scheme $m_{\mathrm{t}}^{\textrm{MSR}}(μ)$ for renormalization scales $μ$ below the $\overline{\textrm{MS}}$ top quark mass $\overline{m}_{\mathrm{t}}(\overline{m}_{\mathrm{t}})$, and in the $\overline{\textrm{MS}}$ scheme $\overline{m}_{\mathrm{t}}(μ)$ for scales above. In particular, the implementation of a mass renormalization scale independent of the strong coupling renormalization scale and factorization scale in quantum chromodynamics allows investigating independent dynamical scale variations. Furthermore, the first theoretically consistent extraction of the top quark MSR mass from experimental data is presented.
