Probing the nature of the $I ¨ _{c 1} (3872)$ state using radiative decays

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1097

The radiative decays $I ¨ _{c 1} (3872) \to I ¨ (2 S) I^^{3}$ and $I ¨ _{c 1} (3872) \to J / I ¨ I^^{3}$ are used to probe the~nature of the~ $I ¨ _{c 1} (3872)$ state using proton-proton collisio…
