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…
