V. V. Bytev, E. A. Kuraev, E. Tomasi-Gustafsson

摘要:

本文计算了$e^- μ^+$辐射散射微分截面的超前对数近似辐射修正。特别是由于光子发射的电子和μ子块的干涉项计算在螺旋度独立和依赖的部分。计算适用于现有的DVCS数据在电子-质子碰撞的运动学条件。考虑了螺旋度奇、偶微分截面。

英文摘要:

Radiative corrections in leading logarithmic approximation are calculated for the differential cross section of $e^- μ^+$ radiative scattering. In particular the interference term due to photon emission from electron and muon blocks are calculated in helicity independent and dependent parts. The calculation is applied to the kinematical conditions of existing DVCS data in electron-proton collisions. Both helicity odd and helicity even differential cross sections are considered.
