Abstract: (arXiv)

A resonance X(3872), first observed in the decays

B \to K X

, has been seen to decay to

J/\psi \pi^+ \pi^-

. The

\pi^+ \pi^-

mass spectrum peaks near its kinematic upper limit, prompting speculation that the dipion system may be in a

\rho^0

. The decay

X(3872) \to J/\psi \omega

also has been observed. The reaction

\gamma \gamma \to J/\psi \pi^+ \pi^-

has been studied. Consequently, angular distributions in decays of

J/\psi (\rho^0,\omega)

states near threshold are of interest, and results are presented.
