对“高精度测定质子的电磁形状因子”一文的答复
Reply to Comment on "High-Precision Determination of the Electric and Magnetic Form Factors of the Proton"
摘要:
在arXiv:1108.3058v1 [nucl-ex]中,Arrington批评了我们在高精度形状因子数据分析中应用的库仑校正(参见Phys.Rev.Lett.105:242001,2010,arXiv:1007.5076v3 [nucl-ex])。我们表明,通过比较不同的计算中引用的评论,评论的批评忽略了“更现代”的TPE校正的大的不确定性。这种不确定性在最近的极化测量中也有所体现。我们用其中一种计算方法来验证我们的分析。结果表明,在Q^2较小的情况下,该评论夸大了数量效应。
英文摘要:
In arXiv:1108.3058v1 [nucl-ex], Arrington criticizes the Coulomb corrections we applied in the analysis of high precision form factor data (see Phys.Rev.Lett.105:242001, 2010, arXiv:1007.5076v3 [nucl-ex]). We show, by comparing different calculations cited in the Comment, that the criticism of the Comment neglects the large uncertainty of "more modern" TPE corrections. This uncertainty has also been seen in recent polarized measurements. We rerun our analysis using one of these calculations. The results show that the Comment exaggerates the quantitative effect at small Q^2.
