Evidence of $I ¨ (3770) \to I ¨ ^{0} J / I ¨ $

BESIII Collaboration, M. Ablikim, M. N. Achasov +766

We report the first evidence for the hadronic transition $I ¨ (3770) \to I ¨ ^{0} J / I ¨ $ using a data sample of $20.3 fb^{- 1}$ collected at $s = 3.773$ ~GeV with the BESIII…

Cross Section Measurements of $n ˉ p \to K^{+} K^{-} I ¨ ^{+} (I ¨ ^{0})$ via Antineutrons Produced by $J / I ¨ \to p I ¨ ^{-} n ˉ$ Decays

BESIII Collaboration, M. Ablikim, M. N. Achasov +759

Based on a novel method for producing antineutrons via $J / I ¨ $ decays, we report a study of $n ˉ p$ inelastic scattering into final states containing kaons. The analysis uses $(1…
