The goal of the joint project is an exploratory investigation of how K* Λ(1116) and K*(0,+) Σ(1193)(+,0) photoproduction off proton and neutron target is associated with the possible formation of multi quark structures, i.e. beyond minimal 3-quark configurations, in the vicinity of the K* production threshold(s). This shall be achieved by the analysis of data taken in the corresponding reaction channels with the BGO-OD experiment. For improved discrimination between kaons and pions it is proposed to take into operation an aerogel Cherenkov detektor in the fringe field of the BGO-OD forward spectrometer.

该联合项目的目标是探索性地研究质子和中子靶的K* Λ（1116）和K*（0，+）Λ（1193）（+，0）光生如何与多夸克结构的可能形成相关联，即在K* 产生阈值附近，超过最小的3夸克结构。这应通过分析BGO-OD实验中相应反应通道中采集的数据来实现。为了提高K介子和π介子之间的鉴别能力，建议在BGO-OD前向谱仪的边缘场中采用气凝胶切伦科夫探测器。
