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…

Search for a dark baryon in the $I^^{-} \to I ¨ ^{-} + invisible$ decay

BESIII Collaboration, M. Ablikim, M. N. Achasov +689

A search for a dark baryon is performed for the first time in the two-body decay $I^^{-} \to I ¨ ^{-} + invisible$ using $(10.087 \pm 0.044) \times 1 0^{9}$ $J / I ¨ $ events collected…
