Observation of exotic $J / I ¨ I ¨ $ resonant structure in diffractive processes in proton-proton collisions

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1072

The first study of $J / I ¨ I ¨ $ production in diffractive processes in proton-proton collisions is presented. The study is based on an LHCb dataset recorded at centre-of-mass energy of…
