Photoproduction of πΔ(1.232) from hydrogen in the energy range 2.4–4.8 GeV

  • Published:
Zeitschrift für Physik C Particles and Fields

Abstract

We present differential cross sections andΔ ++ spin density matrix elements for the photoproduction processγp→π − Δ ++ and differential cross sections for the processγp→π + Δ 0. The incident photon energy dependence is studied and a comparison is made with previous experiments and with the predictions of a theoretical model.

The cross section from hydrogen, however, was 7% lower than the expected value showing that the hydrogen density was lower than that indicated by the temperature and pressure monitors on the target
