Towards a precision determination of the $X (6200)$ parameters from data

Yi-Lin Song, Yu Zhang, Vadim Baru +3

In a recent paper, Phys. Rev. Lett. {\bf 126}, 132001 (2021), the LHCb data on the di- $J / I ¨ $ production in proton-proton collisions were analysed in a coupled-channel framework bas…

Dispersive analysis of the isospin breaking in the $X (3872) \to J / I ¨ I ¨ ^{+} I ¨ ^{-}$ and $X (3872) \to J / I ¨ I ¨ ^{+} I ¨ ^{0} I ¨ ^{-}$ decays

Jorgivan Morais Dias, Teng Ji, Xiang-Kun Dong +5

We analyze the latest LHCb data on the $I ¨ ^{+} I ¨ ^{-}$ spectrum in the isospin-violating $X (3872) \to J / I ¨ I ¨ ^{+} I ¨ ^{-}$ decay, based on dispersion theory to deal with the $I ¨ I ¨ $ final state…
