Production of the X(3872) in charmonia radiative decays
Production of the X(3872) in charmonia radiative decays
We discuss the possibilities of producing the X(3872), which is assumed to be a D \bar D^* bound state, in radiative decays of charmonia. We argue that the ideal energy regions to observe the X(3872) associated with a photon in e^+e^- annihilations are around the Y(4260) mass and around 4.45 GeV, du...

We discuss the possibilities of producing the X(3872), which is assumed to be a D \bar D^* bound state, in radiative decays of charmonia. We argue that the ideal energy regions to observe the X(3872) associated with a photon in e^+e^- annihilations are around the Y(4260) mass and around 4.45 GeV, due to the presence of the S-wave D \bar D_1(2420) and D^* \bar D_1(2420) threshold, respectively. Especially, if the Y(4260) is dominantly a D \bar D_1 molecule and the X(3872) a D \bar D^* molecule, the radiative transition strength will be quite large. We discuss the possibilities of producing the X(3872), which is assumed to be a DD@?^@? bound state, in radiative decays of charmonia. We argue that the ideal energy regions to observe the X(3872) associated with a photon in e^+e^--annihilations are around the Y(4260) mass and around 4.45 GeV, due to the presence of the S-wave DD@?_1(2420) and D^@?D@?_1(2420) threshold, respectively. Especially, if the Y(4260) is dominantly a DD@?_1 molecule and the X(3872) a DD@?^@? molecule, the radiative transition strength will be quite large. |
