In-medium Δ Absorption Cross Section

  • An exact expression for calculating the in-medium △ absorption cross section is obtained within the framework of the self-consistent relativistic BUU approach. The medium effects on the △N→NN cross section is investigated, and it is found that the effective cross sation is suppressed in the medium near the threshold energy. The results are in a good agreement with the most recent experimental data of the TAPS collaboration.

Abstract: An exact expression for calculating the in-medium △ absorption cross section is obtained within the framework of the self-consistent relativistic BUU approach. The medium effects on the △N→NN cross section is investigated, and it is found that the effective cross sation is suppressed in the medium near the threshold energy. The results are in a good agreement with the most recent experimental data of the TAPS collaboration.
