论文摘要
在扰动量子染色性动力学（PQCD）中，可以使用最大的合成性（PMC）来获得极严格的肾小管量子尺度和方案量表的关系，可以获得极限量子的原理（PQCD）在扰动量子染色体动力学（PQCD）中，杆和运行重量的Quark量$ \ Mathcal {o} \ left（α_s^4 \右）$的关系。使用PMC，确定重夸克质量比的最佳重归其化量表，独立于重新归一化的量表和方案，直至$α_s^4 $。然后，将获得重夸克的PMC极质量$ m_b^{\ text {pmc}} = 4.86^{+0.03} _ { - 0.02} $ gev，$ m_t^{ $ \ Overline {M} _T^{\ Text {pmc}} = 162.6 \ pm 0.7 $ GEV在PMC秤上。
The relation of the pole and running heavy quark masses of order $\mathcal{O}\left(α_s^4\right)$ in perturbative quantum chromodynamics (pQCD) can be obtained using the Principle of Maximum Conformality (PMC), a formalism that provides a rigorous method for eliminating renormalization scale and scheme ambiguities for observables in pQCD. Using PMC, an optimal renormalization scale for the heavy quark mass ratio is determined, independent of the renormalization scale and scheme up to order $α_s^4$. Precise values are then obtained for the PMC pole masses of the heavy quarks $M_b^{\text{PMC}}=4.86^{+0.03}_{-0.02}$ GeV, $M_t^{\text{PMC}}=172.3\pm 0.6$ GeV, and the running mass $\overline{m}_t^{\text{PMC}}=162.6\pm 0.7$ GeV at the PMC scale.
