Once more on electromagnetic form factors of nucleons in extended vector meson dominance model

Amand Faessler, M. I. Krivoruchenko, B. V. Martemyanov

摘要:

本文提出了一个扩展的矢量介子优势模型,它能描述服从渐近夸克计数规则规定的核子电磁形状因子,并包含最少的自由参数。我们得到了一个合理的拟合的形状因子在实验上可用的类空区域的动量转移,也得到了合理的结果在类时区域。

英文摘要:

Extended vector meson dominance model, that allows to describe the electromagnetic form factors of nucleons obeying the asymptotic quark counting rule prescriptions and contains the minimal number of free parameters, is presented. We get a reasonable fit of form factors over experimentally available space-like region of momentum transfer and get also reasonable results in the time-like region.
