约束参数下核子的K介子光生

Kaon photoproduction on the nucleon with constrained parameters

R. Nelson, T. Mart

摘要:

本文用多极模型分析了K介子在核子γ p -> K+ λ上光生的新实验数据。与以前的模型不同,在这个分析中,共振衰减宽度被约束到粒子数据组(PDG)给出的值。结果表明,这些参数的PDG值的限制可以显着改变的结论,在这个反应中的重要共振发现在以前的研究。

英文摘要:

The new experimental data of kaon photoproduction on the nucleon, gamma p -> K+ Lambda, have been analyzed by means of a multipoles model. Different from the previous models, in this analysis the resonance decay widths are constrained to the values given by the Particle Data Group (PDG). The result indicates that constraining these parameters to the PDG values could dramatically change the conclusion of the important resonances in this reaction found in the previous studies.
