Gluon orbital angular momentum at small x

We present a general analysis of the orbital angular momentum (OAM) distribution of gluons L_{g}(x) inside the nucleon with particular emphasis on the small-x region. We derive a novel operator representation of L_{g}(x) in terms of Wilson lines and argue that it is approximately proportional to the...
