Buescher (FZ Juelich), W. Cassing (Univ. Giessen | Abstract: | We investigate the cross section for the reaction $NN o NNa_0$ near threshold and at medium energies. An effective Lagrangian approach with one-pion exchange is applied to analyze different contributions to the cross section for different isospin channels. The Reggeon exchange mechanism is also considered. The results are used to calculate the contribution of the $a_0$ meson to the cross sections and invariant $K ar K$ mass distributions of the reactions $pp o pn K^+ar K^0$ and $pp o pp K^+K^-$. It is found that the experimental observation of $a_0^+$ mesons in the reaction $pp o pn K^+ar K^0$ is much more promising than the observation of $a_0^0$ mesons in the reaction $pp o pp K^+K^-$. | Source: | arXiv, nucl-th/0107071 | Services: | Forum | Review | PDF | Favorites |
