Abstract

A perturbative expansion for QED and QCD bound states is formulated in $A^0=0$ gauge. The constituents of each Fock state are bound by their instantaneous interaction. In QCD an O($\alpha_s^0$) confining potential arises from a homogeneous solution of Gauss' constraint. The potential is uniquely determined by the QCD action, up to a universal scale. The Cornell potential is reproduced for quarkonia, and corresponding ones found for higher Fock states, baryons and glueballs.
束缚态和微扰理论
在$A^0=0$规范中给出了QED和QCD束缚态的微扰展开式。每个Fock状态的成分都被它们的瞬时相互作用所束缚。在QCD中,O($\alpha_s^0$)约束势由高斯约束的齐次解产生。这种潜力是唯一由QCD行动决定的,直到一个普遍的规模。康奈尔势在夸子中得到了再现,在更高的Fock态、重子和胶球中也发现了相应的康奈尔势。
