Determination of the X(3872) meson quantum numbers
The quantum numbers of the X(3872) meson are determined to be $J^{PC }= 1^{++}$ based on angular correlations in $B^+ \to X(3872) K^+$ decays, where $X(3872) \to \pi^+\pi^- J/\psi$ and $ J/\psi \to \mu^+\mu^-$. The data correspond to 1.0 fb$^{-1}$ of $pp$ collisions collected by the LHCb detector....
