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…

Partial wave analyses of $I ¨ (3686) \to p p ˉ I ¨ ^{0}$ and $I ¨ (3686) \to p p ˉ I^\cdot$

BESIII Collaboration, M. Ablikim, M. N. Achasov +650

Using a sample of $(2712 \pm 14) \times 1 0^{6}$ $I ¨ (3686)$ events collected with the BESIII detector, we perform partial wave analyses of the decays $I ¨ (3686) \to p p ˉ I ¨ ^{0}$ and $Ï(36…
