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 x^\ensuremath-=\ifmmode±\else\textpm\fi\ensuremath∞. We then use finiteness conditions for the light-cone Hamiltonian to relate the transverse gauge field at x^\ensuremath-=\ifmmode±\else\textpm\fi\ensuremath∞ to the color density integrated over x^\ensuremath-. This result allows us to relate the average transverse momentum of the active quark to color charge correlations in the transverse plane.
