更新了π介子光生数据的SAID分析
Updated SAID analysis of pion photoproduction data
摘要:
能量依赖性和单能量适合现有的π介子光生数据库已更新,以涵盖从阈值到2.7 GeV的实验室光子能量的区域。修订后的共振光衰减耦合已提取和以前的测定相比。显示最近测量的影响。讨论了存在的问题和今后的做法。
英文摘要:
Energy-dependent and single-energy fits to the existing pion photoproduction database have been updated to cover the region from threshold to 2.7 GeV in the laboratory photon energy. Revised resonance photo-decay couplings have been extracted and compared to previous determinations. The influence of recent measurements is displayed. Remaining problems and future approaches are discussed.
