Polarization observables in double neutral pion photoproduction

TAPS Collaboration, T. Seifen, J. Hartmann +73

Measurements of target asymmetries and double-polarization observables for the reaction $γ p \to p π^{0} π^{0}$ are reported. The data were taken with the CBELSA/TAPS experiment at the ELS…

New data on $γ p \to η p$ with polarized photons and protons and their implications for $N^{*} \to N η$ decays

J. Müller, J. Hartmann, M. Grüner +86

The polarization observables $T, E, P, H$ , and $G$ in photoproduction of $η$ mesons off protons are measured for photon energies from threshold to $W = 2400$ MeV ( $T$ ), 2280 MeV ($E…

The polarization observables T, P, and H and their impact on $γ p \to p π^{0}$ multipoles

J. Hartmann, H. Dutz, A. V. Anisovich +76

Data on the polarization observables T, P, and H for the reaction $γ p \to p π^{0}$ are reported. Compared to earlier data from other experiments, our data are more precise and extend t…

The N(1520) 3/2- helicity amplitudes from an energy-independent multipole analysis based on new polarization data on photoproduction of neutral pions

J. Hartmann, H. Dutz, A. V. Anisovich +74

New data on the polarization observables T, P, and H for the reaction $γ p \to p π^{0}$ are reported. The results are extracted from azimuthal asymmetries when a transversely polarized…
