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

Using recent BABAR, CMD-3 and SND data, the sum of $e^+e^- \to 3(\pi^+\pi^-), 2(\pi^+\pi^-\pi^0), p\bar{p}, n\bar{n}$crosssectionsisobtained\mathrm{.}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.
