Quark Model Calculations of the N to Delta Reaction

M. M. Giannini

摘要:

在组分夸克模型的框架下研究了核子共振态的电磁激发。特别注意的是致力于过渡到$Δ$共振和强子系统的可能变形的问题,主要是在连接的问题的四极激发。分析的数据和理论预测之间的差异进行了讨论,并导致重要的结论强子的内部动力学结构。

英文摘要:

The electromagnetic excitation of the nucleon resonances is studied in the framework of Constituent Quark Models. Particular attention is devoted to the transition to the $Δ$ resonance and to the issue of a possible deformation of hadronic systems, mainly in connection with the problem of the quadrupole excitation. The analysis of the emerging discrepancies between data and theoretical predictions is discussed and shown to lead to important conclusions concerning the internal dynamical structure of hadrons.
