The ANL-Osaka Partial-Wave Amplitudes of $\pi N$ and $\gamma N$ Reactions

Understand

The determination of the Argonne National Laboratory-Osaka University (ANL-Osaka) Partial-Wave Amplitudes (PWA) of $\pi N$ and $\gamma N$ Reactions is reviewed.

• The predicted PWA are presented on a web page (https://www.phy.anl.gov/theory/research/anl-osaka-pwa).
• The formulas are given for using the predicted PWA to calculate the cross sections of (1) meson-baryon ($MB$) scattering $MB \rightarrow M'B'$ with $MB, M'B'= \pi N, \eta N, K\Lambda, K\Sigma$, (2) two-pion production $\pi N \rightarrow \pi\Delta, \rho N, \sigma N \rightarrow \pi\pi N$, (3) Meson photoproduction $\gamma N \rightarrow \pi N, \eta N, K\Lambda, K\Sigma$, (4) Pion electroproduction $N(e,e'\pi)N$, (5) inclusive $N(e,e')X$.
• We also present sample results from our fits to the data.
