Time-like electromagnetic form factors of $\mathrm{\Lambda },\mathrm{\Sigma }$ and ${\mathrm{\Xi }}^{+}$ in a light-front quark model

We use the light front quark model to investigate the form factors in the $e^{+}{e}^{-}\to B\bar{B}$ collision proceses with $B=\mathrm{\Lambda },\mathrm{\Sigma }$ and $\mathrm{\Xi }$. These form factor behaviors are calculated based on the Bethe-Salpeter formalism with $q^{+}>0$ to effectively account for non-valence contributions. We show that our results of the $q^2$-dependent form factors closely match the BESIII data. In particalar, we obtain that $\mathrm{\mid }{G}_{eff}\mathrm{\mid }=(0.921,0.098,0.189$) and $R=\mathrm{\mid }$$\frac{G_E}{G_M}$$\mathrm{\mid }=(0.97,0.89$,~$0.936$) for $e^{+}{e}^{-}\to \mathrm{\Lambda }\bar{\mathrm{\Lambda }}$,~${\mathrm{\Sigma }}^{+}{\mathrm{\Sigma }}^{-},{\mathrm{\Xi }}^{+}{\mathrm{\Xi }}^{+})$ which $q^2=(5.74,6.0,7.0)$ GeV${}^2$.
