Remarks on the quantum numbers of X(3872) from the invariant mass   distributions of the rho J/psi and omega J/psi final states
  We re-analyse 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 favour the 1++ assignment for the quantum numbers of the X.
