Energy dependence of $e^{+}{e}^{-}\to 6\pi$ and $e^{+}{e}^{-}\to N\bar{N}$ cross sections near the $N\bar{N}$ threshold

Abstract

Using recent BABAR, CMD-3 and SND data, the sum of $e^{+}{e}^{-}\to 3({\pi }^{+}{\pi }^{-}),2({\pi }^{+}{\pi }^{-}{\pi }^0),p\bar{p},n\bar{n}$ cross sections is obtained. Unlike $e^{+}{e}^{-}\to 3({\pi }^{+}{\pi }^{-})$ and $e^{+}{e}^{-}\to 2({\pi }^{+}{\pi }^{-}{\pi }^0)$ processes, no structures in total cross section are found near the $N\bar{N}$ threshold within the limits of measurement errors.
