论文摘要
电磁形式因素有助于探索核子及其陌生伴侣的内在结构。对于衰减$σ^0 \toλe^+e^ - $，由于相位空间有限，由sigma-to-lambda过渡形式造成的效果与QED辐射校正竞争。这些校正在当前的工作中解决了，超出了软性近似值，即在达利兹图的整个范围内进行评估，并且对辐射光子的能量没有限制。
Electromagnetic form factors serve to explore the intrinsic structure of nucleons and their strangeness partners. For the decay $Σ^0\toΛe^+e^-$, due to limited phase space, the effects caused by the Sigma-to-Lambda transition form factors compete with the QED radiative corrections. These corrections are addressed in the present work, evaluated beyond the soft-photon approximation, i.e., over the whole range of the Dalitz plot and with no restrictions on the energy of the radiative photon.
