Abstract
We analyze the Sivers asymmetry in the light-cone gauge. The average transverse momentum of the quark distribution is related to the correlation between the quark distribution and the transverse component of the gauge field at We then use finiteness conditions for the light-cone Hamiltonian to relate the transverse gauge field at to the color density integrated over This result allows us to relate the average transverse momentum of the active quark to color charge correlations in the transverse plane.
