Does the multiple-scattering series in the pion-deuteron scattering actually converge?

The multiple-scattering series in pion–deuteron scattering and the nucleon–nucleon potential: perspectives from effective field theory

Important contributions to meson–nucleus scattering are produced by terms in the multiple-scattering series, which is defined as the sum of all diagrams where the meson scatters back and forth between a pair of static nucleons before leaving the nucleus. In particular, the sum of this series is needed for an accurate description of kaon– deuteron scattering, and appears as part of the nucleon–n...

Deuteron Compton Scattering below Pion Photoproduction Threshold

Deuteron Compton scattering below pion photoproduction threshold is considered in the framework of the non-relativistic diagrammatic approach with the Bonn OBE potential. The complete gauge-invariant set of diagrams is taken into account which includes resonance diagrams without and with rescattering and diagrams with oneand two-body seagulls. The obtained results are compared with predictions ...

Chiral corrections to the isovector double scattering term for the pion-deuteron scattering length

The empirical value of the real part of the pion-deuteron scattering length can be well understood in terms of the dominant isovector πN -double scattering contribution. We calculate in chiral perturbation theory all one-pion loop corrections to this double scattering term which in the case of πN -scattering close the gap between the current-algebra prediction and the empirical value of the iso...

Pion Deuteron Scattering Length in Effective Field Theory

The S wave pion deuteron scattering length is presented in an effective field theory approach of the two-nucleon system. We include pions as dynamical particles which allows us to calculate pion re-scattering contributions inside the deuteron. Two-nucleon two-pion contact interactions with unknown parameters not determined by chiral symmetry need to be introduced in order to renormalise the app...
