  • We studied the electromagnetic form factors (EMFFs) of Λc and the contributions of the quark and diquark currents to the EMFFs of Λc in the space-like region in the Bethe-Salpeter equation approach with instantaneous approximation. In this picture, baryon Λc can be regarded as a two-body c(ud) system. We found that for different values of parameters the contribution of quark and diquark currents to the EMFFs of Λc is very different, while their total contribution to the EMFFs of Λc is similar. The EMFFs of Λc are similar to those of other baryons (proton, Ξ-, and Σ+) with a peak at ω=1, where ω=v'·v is the velocity transfer between the initial state (with velocity v) and the final state (with velocity v) of Λc.

Abstract: We studied the electromagnetic form factors (EMFFs) of Λc and the contributions of the quark and diquark currents to the EMFFs of Λc in the space-like region in the Bethe-Salpeter equation approach with instantaneous approximation. In this picture, baryon Λc can be regarded as a two-body c(ud) system. We found that for different values of parameters the contribution of quark and diquark currents to the EMFFs of Λc is very different, while their total contribution to the EMFFs of Λc is similar. The EMFFs of Λc are similar to those of other baryons (proton, Ξ-, and Σ+) with a peak at ω=1, where ω=v'·v is the velocity transfer between the initial state (with velocity v) and the final state (with velocity v) of Λc.
