Wong's equations and the small x effective action in QCD - art. no. 036004

We propose a new form for the small x effective action in QCD. This form of the effective action is motivated by Wong's equations for classical, color ed particles in non-Abelian background fields. We show that the BFKL equati on, which sums leading logarithms in x, is efficiently reproduced with this form of the action. We argue that this form of the action may be particula rly useful in computing next-to-leading-order results in QCD at small x.
