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.

联合项目的目的是对K*λ（1116）和K*（0，+）σ（1193）（+，0）质子和中子目标的光增生与多夸克结构的形成相关的探索性研究。这应通过对BGO-OD实验中在相应的反应通道中获取的数据进行分析来实现这一点。为了改善Kaons和Pions之间的区分，建议在BGO-OD前向光谱仪的边缘场中运行一个Air Cherenkov Detektor。
