13 May 2005 | | Subject: | nucl-th hep-ph | | Abstract: | The reaction $gamma d o pi^+ nn$ is calculated up to order $chi^{5/2}$ in chiral perturbation theory, where $chi$ denotes the ratio of the pion to the nucleon mass. Special emphasis is put on the role of nucleon--recoil corrections that are the source of contributions with fractional power in $chi$. Using the known near threshold production amplitude for $gamma p o pi^+ n$ as the only input, the total cross section for $gamma d o pi^+ nn$ is described very well. A conservative estimate suggests that the theoretical uncertainty for the transition operator amounts to 3 % for the computed amplitude near threshold. | | Source: | arXiv, nucl-th/0505039 | | Services: | Forum | Review | PDF | Favorites | |
