Abstract

We investigate the two-dimensional transverse charge distributions of the transversely polarized nucleon. As the longitudinal momentum (PzP_z) of the nucleon increases, the electric dipole moment is induced, which causes the displacement of the transverse charge and magnetization distributions of the nucleon. The induced dipole moment of the proton reaches its maximum value at around Pz3.2P_z \approx 3.2 GeV due to the kinematical reason. We also investigate how the Abel transformations map the three-dimensional charge and magnetization distributions in the Breit frame on to the transverse charge and magnetization ones in the infinite momentum frame.
