双大$N_c$ QCD中强子的电磁形状因子

Electromagnetic Form Factors of Hadrons in Dual-Large $N_c$ QCD

C. A. Dominguez

摘要:

本文介绍了在双大$N_c$ QCD(Dual- $QCD_\infty$)框架下强子(π介子、质子和$Δ(1236)$)电磁形状因子的测定结果。这个框架大大提高了树级VMD的结果,将无限数量的零宽度共振,与固定的双共振(Veneziano型)模型的质量和耦合。

英文摘要:

In this talk, results are presented of determinations of electromagnetic form factors of hadrons (pion, proton, and $Δ(1236)$) in the framework of Dual-Large $N_c$ QCD (Dual-$QCD_\infty$). This framework improves considerably tree-level VMD results by incorporating an infinite number of zero-width resonances, with masses and couplings fixed by the dual-resonance (Veneziano-type) model.
