Electric Sachs Form Factors of Low-Lying Octet Baryons in a Spectator Diquark Model
摘要
Electromagnetic properties of a hadron are analyzed to elucidate the distribution of charge and magnetization within a hadron. Sachs form factors are the fundamental quantities used to study these properties. We have adopted the light-cone formalism to analyze the electric Sachs form factors \(G_E(Q^2)\) of strange and non-strange low-lying octet baryons in a diquark spectator model. All possible polarization states of a diquark are considered with the dipolar form factor of the baryon-quark-diquark vertex. The computed results of \(G_E(Q^2)\) are presented with the comparison of available data for both strange and non-strange low-lying octet baryons.
