在微扰QCD中,我们导出了用量子数n,k,s和j标识的重夸克偶素态能级的完整公式,直到O(α s 5 m)和O(α s 5 m log k α s).给出了QCD Bethe对数的单参数积分形式。该公式的其余部分是有理数、超越数(π,π(3),π(5))和有限和的组合(除了静态势的3圈常数a <$3,其完整的解析形式仍然未知)。给出了公式的推导过程。
We derive a full formula for the energy level of a heavy quarkonium state identified by the quantum numbers n, ℓ, s and j, up to O (α s 5 m) and O (α s 5 m log⁡ α s) in perturbative QCD. The QCD Bethe logarithm is given in a one-parameter integral form. The rest of the formula is given as a combination of rational numbers, transcendental numbers (π, ζ (3), ζ (5)) and finite sums (besides the 3-loop constant a¯ 3 of the static potential whose full analytic form is still unknown). A derivation of the formula is given.
