Search for the process $e^{+}{e}^{-}\to \hat{I}{\cdot }^{\prime }{\hat{I}}^3$ in the energy range $\sqrt{s}$ = 1.075 -- 2 GeV

Abstract

The results of the search for the $e^{+}{e}^{-}\to \hat{I}{\cdot }^{\prime }{\hat{I}}^3$ process in the center-of-mass energy range from 1.075 to 2 GeV are presented. We analyze data with an integral luminosity of 746 pb${}^{-1}$ accumulated with the SND detector at the $e^{+}{e}^{-}$ collider VEPP-2000 in 2010--2024. The $\hat{I}{\cdot }^{\prime }\to \hat{I}\cdot \ddot{I}{€}^0\ddot{I}{€}^0$ decay is used in the analysis, with the subsequent $\hat{I}\cdot$ and $\ddot{I}{€}^0$ decays into ${\hat{I}}^3{\hat{I}}^3$. Upper limits not exceeding 13 pb have been set on the $e^{+}{e}^{-}\to \hat{I}{\cdot }^{\prime }{\hat{I}}^3$ cross section at the 90\% confidence level.
