Progress in NN --> NNpi
V. Baru, J. Haidenbauer, C. Hanhart +3
We survey the recent developments in the reaction in effective field theory. We show that the proper construction of the production operator needs a careful separation…
Pion--deuteron scattering length in Chiral Perturbation Theory up to order χ^{3/2}
V. Baru, J. Haidenbauer, C. Hanhart +3
A complete calculation of the corrections to pion-deuteron scattering length up to order with is performed. The calculation includes the dispersive contribu…
Role of the Delta(1232) in pion-deuteron scattering at threshold within chiral effective field theory
V. Baru, J. Haidenbauer, C. Hanhart +3
We investigate the role of the delta isobar in the reaction at threshold in chiral effective field theory. We discuss the corresponding power counting and argue that thi…
Neutron-neutron scattering length from the reaction gamma d --> pi^+ nn employing chiral perturbation theory
V. Lensky, V. Baru, E. Epelbaum +4
We discuss the possibility to extract the neutron-neutron scattering length a_{nn} from experimental spectra on the reaction gamma d --> pi^+ nn. The transition operator is calcula…
