论文摘要

我们在动量传递区域中重新分析了电子 - 普罗替子散射数据$ q^2 <1 \ gev^2 $,这些数据用于确定质子电动半径,主要关注Mainz实验(Bernauer等,2010)。我们使用pseudo-data检查了拟合结果的依赖性和$ q^2 $对截止的临界值和拟合多项式的程度,并将其与真实实验数据的情况进行比较。我们发现,在某些假设下,数据可能与从Muonic氢获得的半径一致。

We reanalyze electron-proton scattering data in the momentum transfer region $Q^2 < 1\ GeV^2$, which were used to determine proton electric radius, with main focus on the Mainz experiment (Bernauer et al., 2010). We examine dependence of fit results and $χ^2$ on the cut-off in $Q^2$ and degree of fitting polynomial, using pseudo-data and compare it with the case of real experimental data. We find that under some assumptions, the data could be consistent with the radius, obtained from muonic hydrogen.
