Dispersion-theoretical analysis of the electromagnetic form factors of the $$\Lambda $$ Λ hyperon

Abstract The electromagnetic form factors of the $$\Lambda $$ Λ hyperon in the time-like region are determined precisely through a dispersion-theoretical analysis of the world data for the cross section of the annihilation process $$e^+e^-\rightarrow {\bar{\Lambda }}{\Lambda }$$ e + e - → Λ ¯ Λ .
