  1. Abstract

    The differential cross section for the quasi-free photoproduction reaction$$\gamma n\rightarrow K^0\Sigma ^0$$γnK0Σ0was measured at BGOOD at ELSA from threshold to a centre-of-mass energy of$$2400\,\hbox {MeV}$$2400MeV. Close to threshold the results are consistent with existing data and are in agreement with partial wave analysis solutions over the full measured energy range, with a large coupling to the$$\Delta (1900)1/2^-$$Δ(1900)1/2-evident. This is the first dataset covering the$$K^*$$Kthreshold region, where there are model predictions of dynamically generated vector meson-baryon resonance contributions.

    Abstract $$\gamma p \rightarrow K^{+} \Lambda $$ γ p → K + Λ differential cross sections and recoil polarisation data from threshold for extremely forward angles are presented. The measurements were performed at the BGOOD experiment at ELSA, utilising the high angular and momentum resolution forward spectrometer for charged particle identification. The high statistics and forward angle acceptance enables the extraction of the cross section as the minimum momentum transfer to the recoiling hyperon is approached.
