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…

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…
