\(\gamma p \rightarrow K^{+} \Lambda \) 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.

$$ K ^ {+} \ Lambda $$ K +Λ以正向角度和低动量传递进行照相生产

给出了（（gamma p \ rightarrow K ^ {+} \ Lambda \）微分截面和来自极前角阈值的反冲极化数据。测量是在ELSA的BGOOD实验中进行的，利用高角度和动量分辨率正向光谱仪进行带电粒子识别。高统计量和前向角验收可以在接近最小动量传递到反冲超子的情况下提取横截面。
