Abstract

Amplitude analysis is a powerful tool to study the properties of intermediate resonances produced in the decays of B mesons. At LHCb we have studied B+ decays to X(3872) K+, where X(3872) decays to J/psi pi+ pi-, to determine the quantum numbers of the X(3872), and B+ decays to proton anti-proton K+ to learn more about (charm anti-charm) to proton anti-proton transitions. We also exploit the spin of the J/psi to perform amplitude analyses of the decays B0_s to J/psi pi+ pi-, B0_s to J/psi K+ K-, B0 to J/psi pi+ pi-, and B0 to J/psi K+ K-. Our results use 1.0 inverse femtobarn of data taken in 2011 from 7 TeV proton-proton collisions, provided by the LHC.
