Helicity-dependent cross sections for the photoproduction of $π^{0}$ pairs from nucleons

M. Dieterle, L. Witthauer, A. Fix +88

The double-polarization observable $E$ and helicity-dependent cross sections $σ_{1/2}$ , $σ_{3/2}$ have been measured for the photoproduction of $π^{0}$ pairs off quasi-free protons a…

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…
