标题： Electromagnetic proton form factors in large $N_{c}$ QCD

摘要： 电磁质子的电磁形式因子是通过QCD在大$N_c$极限下的特定实现（${QCD}_{\infty}$）获得的，这将无限多个零宽度共振求和以产生欧拉的贝塔函数（对偶-${QCD}_{\infty}$）。 形式因子$F_1(q^2)$和$F_2(q^2)$，以及$G_M(q^2)$在整个动量转移范围内与重新分析的类空数据非常吻合。 此外，预测的比值$\mu_p G_E/G_M$与杰弗逊实验室最近的极化传递测量结果相符。 显示英文摘要

摘要： The electromagnetic form factors of the proton are obtained using a particular realization of QCD in the large $N_c$ limit (${QCD}_{\infty}$), which sums up the infinite number of zero-width resonances to yield an Euler's Beta function (Dual-${QCD}_{\infty}$). The form factors $F_1(q^2)$ and $F_2(q^2)$, as well as $G_M(q^2)$ agree very well with reanalyzed space-like data in the whole range of momentum transfer. In addition, the predicted ratio $\mu_p G_E/G_M$ is in good agreement with recent polarization transfer measurements at Jefferson Lab.
