Fock space distributions, structure functions, higher twists, and small x

“…Bothof these can be computed explicitly from the small fluctuations propagator in the classical background field. The propagator was first computed by fixing the residual gauge freedom to be δA − (x − = 0)[17] but a less restrictive gauge choice was later found which may be useful for computing σ and χ[20].…”

What’s new at small x?

“…Quantum corrections to the classical EFT give large logs in α S ln(1/x) [28]. A Wilson renormalization group procedure was devised which sums up these large logs [6].…”
