Absorption corrections or B-exchange as the major secondary contribution in π+n → ωp
A comparison between experimental data for π +n → ωp and theory is made to determine whether in addition to the expected ϱ- contribution a B-meson or an absorption correction is the major secondary contribution. It was found that the B-meson gave a better description for the secondary contribution t...

| Summary: | A comparison between experimental data for
π
+n →
ωp and theory is made to determine whether in addition to the expected ϱ- contribution a B-meson or an absorption correction is the major secondary contribution. It was found that the B-meson gave a better description for the secondary contribution than the inclusion of absorption to the dominant ϱ-meson contribution. In both cases the ϱ-amplitudes are found to prefer no α-factors as suggeted by the Mandelstam-Wang mechanism. |
