The project will analyse data collected from the CLAS12 experiment based in Hall B, Jefferson Lab, US. The reaction of interest uses an electron beam on a proton target to produce mesons which subsequently decay to 2 pions. Here we detect small angle scattered electrons to provide a large flux of events in a new Forward Tagger providing quasi-real virtual photons. The pions are detected in the CLAS12 spectrometer. After reconstructing the particle four momentum an decay angle analysis will be performed to investigate which mesons were produced on the production process.

该项目将分析从CLAS12实验收集的数据，该实验位于美国杰斐逊实验室的B厅。感兴趣的反应使用质子靶上的电子束产生介子，随后衰变为2 π。在这里，我们检测小角度散射电子提供一个新的向前标记提供准真实的虚光子的事件的大流量。π介子在CLAS12谱仪中被探测到。在重建粒子四动量后，将进行衰变角分析以研究在产生过程中产生了哪些介子。
