Potential of the reaction $e^{+}{e}^{-}\to p\bar{p}\ddot{I}{€}^0$ for constructing higher $\ddot{I}$-meson spectroscopy above 2.4 GeV

Dan Guo, Jun-Zhang Wang, Qin-Song Zhou

The spectrum of light unflavored vector mesons above 2.4 GeV has not yet been firmly established experimentally. In this work, we demonstrate that the process $e^+e^- \to p\bar{p}Ï…
