摘要：

A resonance X(3872), first observed in the decays B-->KX, has been seen to decay to J/psipi(+)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)-->J/psiomega also has been observed. The reaction gammagamma-->J/psipi(+)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.
