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…

Measurement of the $I^_{c}^{+}$ to $D^{0}$ production cross-section ratio in peripheral PbPb collisions

LHCb collaboration

We report on a measurement of the $I^_{c}^{+}$ to $D^{0}$ production ratio in PbPb collisions at $s_{NN}$ = 5.02 TeV with the LHCb detector in the forward rapidity region $2 <y…

Comprehensive analysis of local and nonlocal amplitudes in the $B^{0} \to K^{* 0} I^¼^{+} I^¼^{-}$ decay

LHCb collaboration, R. Aaij, A. S. W. Abdelmotteleb +1073

A comprehensive study of the local and nonlocal amplitudes contributing to the decay $B^{0} \to K^{* 0} (\to K^{+} I ¨ ^{-}) I^¼^{+} I^¼^{-}$ is performed by analysing the phase-space distrib…
