virtual photon necessary for applications at next-to-leading order (NLO) in the QCD …

Nonperturbative QCD: A weak-coupling treatment on the light front

KG Wilson, TS Walhout, A Harindranath, WM Zhang… - Physical Review D, 1994 - APS
In this work the determination of low-energy bound states in quantum chromodynamics is
recast so that it is linked to a weak-coupling problem. This allows one to approach the …

Massive quarks at one loop in the dipole picture of deep inelastic scattering

G Beuf, T Lappi, R Paatelainen - Physical Review Letters, 2022 - APS
We calculate the light cone wave functions for a virtual photon to split into quark-antiquark
states, including for the first time quark masses at one loop accuracy. These wave functions …
