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…

Hyperon II: Properties of excited hyperons

A. V. Sarantsev, M. Matveev, V. A. Nikonov +3

We report properties of $Λ$ and $Σ$ hyperon resonances formed in $K^{-}$ induced reactions. Special emphasis is laid on the analysis of the three-body final states $2 π^{0} Λ$ and $2π^0Σ…

Hyperon I: Partial wave amplitudes for $K^{-} p$ scattering

M. ~Matveev, A. V. ~Sarantsev, V. A. Nikonov +3

Early data on $K^{-}$ induced reactions off protons are collected and used in a coupled-channel partial wave analysis (PWA). Data which had been published in the form of Legendre coe…
