Cross section measurement of $e^{+} e^{-} \to I^\cdot I ¨ (2 S)$ and search for $e^{+} e^{-} \to I^\cdot X ~ (3872)$

BESIII Collaboration, M. Ablikim, M. N. Achasov +645

The energy-dependent cross section for $e^{+} e^{-} \to I^\cdot I ¨ (2 S)$ is measured at eighteen center of mass energies from 4.288 GeV to 4.951 GeV using the BESIII detector. Using the same da…
