Production of doubly-charged $\Delta$ baryon in $e^{+}{e}^{-}$ annihilation at energies from 2.3094 to 2.6464 GeV

BESIII Collaboration, M. Ablikim, M. N. Achasov +591

The processes $e^{+}{e}^{-}\to {\Delta }^{++}{\bar{\Delta }}^{--}$ and $e^{+}{e}^{-}\to {\Delta }^{++}\bar{p}{\pi }^{-}+c.c.$ are studied for the first time with $179{\mathrm{pb}}^{-1}$ of $e^{+}{e}^{-}$ annihilation…
