Nucleon-deuteron capture with chiral potentials
Present day chiral nucleon-nucleon potentials up to next-to-next-to-next-to leading order and three nucleon forces at next-to-next-to leading order are used to analyze nucleon-deuteron radiative capture at deuteron laboratory energies below E-d approximate to 100 MeV.

Present day chiral nucleon-nucleon potentials up to next-to-next-to-next-to leading order and three nucleon forces at next-to-next-to leading order are used to analyze nucleon-deuteron radiative capture at deuteron laboratory energies below E-d approximate to 100 MeV. The differential cross section and the deuteron analyzing powers A(y)(d) and A(yy) are presented and compared to data. The theoretical predictions are obtained in the momentum-space Faddeev approach using the nuclear electromagnetic current operator with exchange currents introduced via the Siegert theorem. The chiral forces provide the same quality of data description as a combination of the two-nucleon AV18 and the three-nucleon Urbana IX interactions. However, the different parametrizations of the chiral potentials lead to broad bands of predictions. |
