论文摘要
我们提供了对电子蛋白散射最近日期的分散理论分析。这允许高精度提取质子的电和磁性半径,$ r_e =(0.839 \ pm 0.002 {}^{+0.002} _ { - 0.003})$ 〜fm和$ fm and $ r_m =(0.846 \ pm 0.001 \ pm 0.001 {}^}^{}+0.001}^{+0.001}从Bootstrap方法估计的统计类型,第二种是指与基础光谱函数相关的系统不确定性。
We present a dispersion theoretical analysis of recent date from electron-proton scattering. This allows for a high-precision extraction of the electric and magnetic radius of the proton, $r_E = (0.839\pm 0.002{}^{+0.002}_{-0.003})$~fm and $r_M = (0.846\pm 0.001{}^{+0.001}_{-0.005})$~fm, where the first error refers to the statistical type estimated from the bootstrap method, and the second one refers to the systematic uncertainty related to the underlying spectral functions.
