The first full amplitude analysis of $B^+ \to J/\psi\phi K^+$ with $J/\psi \to \mu^+\mu^−, \phi \to K^+ K^−$ decays is performed with a data sample of 3 $fb^{−1}$ of $pp$ collision data collected at $\sqrt{s}=7$ and 8 TeV with the LHCb detector. The data cannot be described by a model that contains only excited kaon states decaying into $\phi K^+$, and four $J/\psi\phi$ structures are observed, each with significance over 5 standard deviations. The quantum numbers of these structures are… CONTINUE READING
