论文摘要
为了从电子散射数据中提取质子的电荷半径，$ r_ {p} $，杰斐逊实验室的PRAD协作开发了一个严格的框架，用于从各种范围和不遗产的PRAD数据范围内从多种样本功能中找到最佳功能形式 - 钳工。在本文中，我们利用并进一步开发此框架。本文中，我们讨论了搜索最佳钳工候选者的方法，以及通过基于基于弹性电子 - 脱氧核糖核物散射数据的参数化来测试Deuteron电荷半径（$ R_ {d} $）鲁棒性的过程。本文在本文中提出的$ r_ {d} $的鲁棒提取，对于杰斐逊实验室的拟议低 - $ q^{2} $ drad实验，一旦有更多数据，就可以进一步改进。
To extract the charge radius of the proton, $r_{p}$, from the electron scattering data, the PRad collaboration at Jefferson Lab has developed a rigorous framework for finding the best functional forms - the fitters - for a robust extraction of $r_{p}$ from a wide variety of sample functions for the range and uncertainties of the PRad data. In this paper we utilize and further develop this framework. Herein we discuss methods for searching for the best fitter candidates as well as a procedure for testing the robustness of extraction of the deuteron charge radius, $r_{d}$, from parametrizations based on elastic electron-deuteron scattering data. The ansatz proposed in this paper for the robust extraction of $r_{d}$, for the proposed low-$Q^{2}$ DRad experiment at Jefferson Lab, can be further improved once there are more data.
