Two-dimensional transverse charge distributions of the nucleon and Abel transformations

초록

In the present talk we discuss a recent work on the transverse charge distributions of the transversely polarized nucleon with the nucleon momentum varied. As the longitudinal momentum (Pz) of the nucleon increases, the electric dipole moment is induced, which brings about 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 Pz=3.2 GeV on account of the kinematical reason. We also show how the Abel transformations map the three-dimensional charge and magnetization distributions in the Breit frame onto the transverse charge and magnetization ones in the infinite momentum frame.
