The energy dependence of forward angle pion double charge exchange is calculated in the energy range of 0‐250 MeV. The most striking feature is a peak around 40 MeV which is in excellent agreement with the data when distorted waves obtained from a

$\ensuremath{\pi}\ensuremath{\pi}$ scattering amplitudes inside the subthreshold triangle $(0l~sl~\ensuremath{\Sigma}$, $0l~tl~\ensuremath{\Sigma}$, $0l~ul~\ensuremath{\Sigma}=4{\ensuremath{\mu}}^{2})$ are studied using interior dispersion relations.

The on-shell ππ scattering amplitudes within and on the boundary of the subthreshold triangle (0 ≤ s ≤ Σ , 0 ≤ t ≤ Σ , 0 ≤ u ≤ Σ ≡ 4 μ 2 ) are investigated. Interior Dispersion Relations, when combined with experimental ππ phase

We have analyzed low-energy pion-nucleon data for isospin invariance by comparing charge-exchange amplitudes derived from charge-exchange data with those predicted from recent {pi}{sup {plus_minus}}{ital p} elastic data through the application of iso

We investigate the behavior of the operator responsible for sequential pion double charge exchange in nuclei in the plane wave limit with a view to studying its extension in space, especially the short-range part.

Current algebra and partially controlled axial-vector current ~PCAC! make powerful predictions in the threshold and subthreshold regions of the pN system @1#. Some of the most important examples are the Adler consistency condition @2# ~which predicts
This paper contains the results of an analysis of recent low-energy pion-nucleon scattering experiments. Obtained are phase shifts, the pion-nucleon coupling constant and an estimate of the Sigma term.

Antinucleon-nucleus elastic scattering is addressed from the point of view of the off-shell properties of the two-body {ital {bar p}}-nucleon system. The energy dependence of the interaction is studied. Comparison with {ital {bar p}}-{sup 12}C elasti
