13 Mar 2008 | | Abstract: | The reaction $e^+e^- oomegapi^0$ is investigated in the $^3P_0$
nonrelativistic quark model. The experimental data of the process are fairly
reproduced in the work. The study suggests that at the energy region from the
threshold to 1.5 GeV the two-step process, in which the primary $ar qq$ pair
first forms a vector meson then the meson decays into a hadron pair, is
dominant over the one-step process in which the primary $ar qq$ pair is
directly dressed by an additional $ar qq$ pair to form a hadron pair. It is
found that the experimental data of the reaction $e^+e^- oomegapi^0$
strongly dictate a $2S$ $
ho(1450)$ meson. | | Source: | arXiv, 0803.2028 | | Services: | Forum | Review | PDF | Favorites | |
