Analyzing powers and cross sections ofp→p→pnπ+

Pion reactions with few-nucleon systems

“…Clearly, although all data presented in Ref. [42] are in a good agreement with our calculation (see left panel in Fig. 6 and also Ref.…”

“…However, the partial wave analysis of Ref. [42] seems to be not correct. Here we refer the interested reader to Ref.…”

“…Instead, they were compared to the results of the partial wave analysis (PWA) performed in Ref. [42], as demonstrated in the right panel of Fig. 6.…”

NN → NNπ from the effective field theory point of view: short comings and gains

“…We find it very gratifying that chiral symmetry provides a direct connection between pion production at energies ∼ 350 MeV (IUCF) and N d scattering at energies ∼ 10 MeV (Madison, TUNL). [14].…”

“…The desired observable is the amplitude of the 1 S 0 → 3 S 1 p transition (a 0 ), recently extracted from data of the reaction pp → pnπ + [14]. In Fig.…”
