The perturbative accuracy for bottomonium observables has recently been extended to next-to-next-to-next-to-leading order. Assuming the hierarchy Λ QCD (cid:28) m b v 2 holds, non-perturbative effects take the form of local condensates. I determine higher-order corrections in this approach and assess its validity by studying the convergence of the series. In particular, the non-perturbative effects on the determination of the bottom-quark mass from the bottomonium spectrum and sum rules are discussed.
底态观测的微扰精度最近被扩展到次-次-次-次-先阶。假设层次结构Λ QCD (cid:28) m b v2成立，非微扰效应采取局部凝聚的形式。我确定了这种方法的高阶修正，并通过研究级数的收敛性来评估其有效性。特别地，讨论了从底态谱和和规则确定底夸克质量的非微扰效应。

The covariant variational approach to Yang-Mills theory is further developed. After discussing the foundations of the method both at zero and finite temperature, we briefly recall the effective action for the Polyakov loop and the critical properties of the deconfinement phase transition within this approach. The thermodynamics of pure Yang-Mills theory are studied in detail and the resulting equation of state is compared to lattice data. While there is good agreement in the deconfined (high-temperature) phase, a small but non-zero pressure is predicted in the confined phase at low temperatures, in contrast to physical expectations. We propose possible improvements to address this issue. Finally, we discuss the combination of the variational approach with Dyson-Schwinger techniques and argue that the method can be used as a tool to determine the optimal vertices for a truncated set of Dyson-Schwinger equations. We briefly lay out how this technique could be applied to Yang-Mills theory at zero temperature.
