Rosenbluth分离技术改进的辐射修正和质子电荷形状因子

Improved radiative corrections and proton charge form factor from the Rosenbluth separation technique

Florian Weissbach, Kai Hencken, Dirk Trautmann, Ingo Sick

摘要:

我们调查是否质子电形状因子从测量使用Rosenbluth分离技术和极化转移方法之间的明显差异是由于辐射校正程序中采用的标准近似。在我们的模拟方法中,由于峰值近似和软光子近似的不准确性已被删除。与(e,e'p)实验的结果相反,我们发现它们在这种情况下太小,无法解释这种差异。

英文摘要:

We investigate whether the apparent discrepancy between proton electric form factor from measurements using the Rosenbluth separation technique and polarization transfer method is due to the standard approximations employed in radiative correction procedures. Inaccuracies due to both the peaking approximation and the soft-photon approximation have been removed in our simulation approach. In contrast to results from (e,e'p) experiments, we find them in this case to be too small to explain the discrepancy.
