电子-质子弹性散射中的双光子交换:理论更新

Two-Photon Exchange in Electron-Proton Elastic Scattering: Theory Update

Andrei V. Afanasev

摘要:

本文综述了近年来电子-质子弹性散射中双光子交换效应的理论研究进展。双光子交换机制被认为是一个可能的来源之间的差异极化和非极化的质子电形状因子的实验测量在几个GeV的$^2$动量转移。这种机制预测了目前实验研究的可测量的效果。

英文摘要:

Recent theoretical developments in the studies of two-photon exchange effects in elastic electron-proton scattering are reviewed. Two-photon exchange mechanism is considered a likely source of discrepancy between polarized and unpolarized experimental measurements of the proton electric form factor at momentum transfers of several GeV$^2$. This mechanism predicts measurable effects that are currently studied experimentally.
