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…

Photoproduction of $K^{+} Λ (1405) \to K^{+} π^{0} Σ^{0}$ extending to forward angles and low momentum transfer

G. Scheluchin, T. C. Jude, S. Alef +32

$K^{+} Λ (1405)$ photoproduction has been studied at the BGOOD experiment via the all neutral decay, $Λ (1405) \to Σ^{0} π^{0}$ . The unique BGOOD experimental setup allows both the cro…

$K^{+} Λ$ (1405) photoproduction at the BGO-OD experiment

Georg Scheluchin, Stefan Alef, Patrick Bauer +30

Since the discovery of the $Λ (1405)$ , it remains poorly described by conventional constituent quark models, and it is a candidate for having an "exotic" meson-baryon or "penta-quar…
