| Publication Abstract: | We investigate how the charge distributions of both the unpolarized and transversely polarized ? baryon change as the longitudinal momentum~(Pz) of the ? baryon increases from Pz=0 to Pz=? in a Wigner phase-space perspective. When the ? baryon is longitudinally polarized, its two-dimensional charge distribution is kept to be spherically symmetric with Pz varied, whereas when the ? baryon is transversely polarized along the x-axis, the quadrupole contribution emerges at the rest frame (Pz=0). When Pz grows, the electric dipole and octupole moments are induced. The induced dipole moment dominates over other higher multipole contributions and governs the deformation of the charge distribution of the ? baryon. |
