Productions of X(1835) as baryonium with sizable gluon content | Gui-Jun Ding

15 Nov 2005 | Abstract: | The X(1835) has been treated as a baryonium with sizable gluon content, and to be almost flavor singlet. This picture allows us to rationally understand X(1835) production in $J/psi$ radiation decay, and its large couplings with $par{p}$, $eta^{prime}pipi$. The processes $Upsilon(1S) o gamma X(1835)$ and $J/psi o omega X(1835)$ have been examined. It has been found that $Br(Upsilon(1S) ogamma X(1835))Br(X(1835) o par{p})<6.45 imes10^{-7}$, which is compatible with CLEO’s recently experimental result (hep-ex/0510015). The branching fractions of $Br(J/psi oomega X(1835))$, $Br(J/psi ophi X(1835))$, $Br(J/psi o
ho X(1835))$ with $X(1835) o par{p}$ and $X(1835) oeta^{prime}pi^{+}pi^{-}$ have been estimated. We show they are heavily suppressed by fragmentation of light quarks. The experimental checks for these estimations are expected. The existence of baryonium nonet is conjectured, and a model independent derivation to their production branching fractions is presented. | Source: | arXiv, hep-ph/0511186 | Services: | Forum | Review | PDF | Favorites |
