Abstract
Background: Measurements of the polarization observables Σ, P, T, Ox, Ozfor the reaction →𝛾p →K⁰SΣ⁺ using a linearly polarized photon beam of energy 1.1 to 2.1 GeV are reported.
Purpose: The measured data provide information on a channel that has not been studied extensively, but is required for a full coupled-channel analysis in the nucleon resonance region.
Method: Observables have been simultaneously extracted using likelihood sampling with a Markov-Chain Monte Carlo process.
Results: Angular distributions in bins of photon energy Eγ are produced for each polarization observable. T,Ox,and Ozare first time measurements of these observables in this reaction. The extraction of Σ extends the energy range beyond a previous measurement. The measurement of P, the recoil polarization, is consistent with previous measurements.
Conclusions: The measured data are shown to be significant enough to affect the estimation of the nucleonresonance parameters when fitted within a coupled-channels model.
