Photoproduction of Neutral Pions off Protons

The CBELSA/TAPS collaboration Crede, V. ; Sparks, N. ; Wilson, A. ; et al.

Phys.Rev.C 84 (2011) 055203, 2011.

https://inspirehep.net/literature/917921 Inspire Record 917921 DOI 10.17182/hepdata.61486 https://doi.org/10.17182/hepdata.61486

Photoproduction of neutral pions has been studied with the CBELSA/TAPS detector in the reaction $\gamma p\to p\pi^0$ for photon energies between 0.85 and 2.50 GeV. The $\pi^0$ mesons are observed in their dominant neutral decay mode: $\pi^0\to\gamma\gamma$. For the first time, the differential cross sections cover the very forward region, $\theta_{\rm c.m.}<60^\circ$. A partial-wave analysis of these data within the Bonn-Gatchina framework observes the high-mass resonances $G_{17}$(2190), $D_{13}$(2080), and $D_{15}$(2070).

Pion production with polarized photons and test of vector dominance model

Geweniger, Chr. ; Heide, P. ; Kötz, U. ; et al.

Phys.Lett.B 28 (1968) 155-156, 1968.

https://inspirehep.net/literature/1392676 Inspire Record 1392676 DOI 10.17182/hepdata.29098 https://doi.org/10.17182/hepdata.29098

Cross section asymmetries for the sum of single π + and π - production with polarized photons of 3.4 GeV have been measured. The results disagree with calculations based on the vector dominance model using experimental data of vector meson production in π beams.
