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…
Pion reactions on two--nucleon systems
C. Hanhart
We review recent progress in our understanding of elastic and inelastic pion reactions on two nucleon systems from the point of view of effective field theory. The discussion inclu…
