Description

We study the transverse spatial distribution of orbital angular momentum (OAM) in the nucleon at peripheral distances b∼1/Mπ. Chiral EFT is used to compute the form factors of the energy-momentum tensor and their peripheral transverse densities, including the density associated with light-front orbital angular momentum. This density is represented in first–quantized form, as overlap integral of chiral light–front wave functions describing the transition of the nucleon to soft pion–nucleon intermediate states. We identify the operator generating OAM densities in transverse coordinate space and argued that under a fist-quantized framework interpretation, it properly describes the structure of OAM contributions in the nucleon’s periphery.
