Derives relativistic spatial distributions of transverse orbital angular momentum, intrinsic spin, and total angular momentum in the transverse plane for spin-0 and spin-1/2 targets via quantum phase-space formalism and verifies the transverse spin sum rule.
Relativistic EMT distributions in polarized nucleons recover good and bad light-front components in the IMF after including polarization effects.
A modified non-separable LFWF ansatz for pseudoscalar heavy quarkonia enables computation of zero-skewness GPDs, EM and gravitational form factors, and transverse distributions within the Schwinger-function framework.
Nucleon EM form factors computed in instanton vacuum model with parameters fixed by saddle-point equation yield proton charge radius 0.841 fm matching muonic hydrogen and good agreement on Q2 dependence of ratios.
