Lowest order QED radiative corrections to five-fold differential cross section of hadron leptoproduction
摘要：
首次精确计算了独占辐射尾对半包含强子轻子产生截面的贡献。虽然包容性数据分析的经验表明，从弹性峰辐射尾部的贡献是特别重要的，类似的影响，在半包容性的过程中，只是最近估计的峰值近似。得到了辐射尾对五重微分截面的最低阶QED贡献的轻子部分的显式表达式，并进行了讨论。数值估计，在杰斐逊实验室的运动学条件下提供，表现出相当大的影响，在该地区的独家辐射尾在半包容性的阈值和高能量的检测强子。
英文摘要：
The contribution of exclusive radiative tail to the cross section of semi-inclusive hadron leptoproduction has been calculated exactly for the first time. Although the experience of inclusive data analyses suggests us that the contribution of radiative tail from the elastic peak is of particular importance, similar effects in the semi-inclusive process were only recently estimated in the peaking approximation. The explicit expressions for the lepton part of the lowest order QED contribution of exclusive radiative tail to the five-fold differential cross section are obtained and discussed. Numerical estimates, provided within Jefferson Lab kinematic conditions, demonstrate rather large effects of the exclusive radiative tail in the region at semi-inclusive threshold and for high energy of detected hadron.
