Remarks on the quantum numbers of X(3872) from the invariant mass distributions of the ρJ/ψ and ωJ/ψ final states

We reanalyze the two- and three-pion mass distributions in the decays X(3872) -> rho J/psi and X(3872) -> omega J/psi and argue that the present data favor the 1(++) assignment for the quantum numbers of the X.
