论文摘要
在电磁电子质子相互作用的现象学描述中，已经计算出弹性电子质子散射的差分横截面。该计算基于对角度自旋的质子电流矩阵元素的一致评估，这使得可以自然地获得广义sachs形式的表达式。在弹性$ e \ e \ vec {p} \ to e \ vec {p} $过程中，在静止的初始质子沿最终质质子运动的方向完全极化的情况下，已经提出了一种新方法来独立测量这些形式。
The differential cross section for elastic electron proton scattering has been calculated taking into account the two photon exchange within the phenomenological description of the electromagnetic electron proton interactions. The calculation is based on the consistent evaluation of the matrix elements of the proton current in a diagonal spin basis, which makes it possible to naturally obtain expressions for the generalized Sachs form factors. A new method has been proposed to independently measure these form factors in the elastic $e \vec{p} \to e \vec{p}$ process in the case where the initial proton at rest is fully polarized along the direction of the motion of the final proton.
