论文摘要
我们计算了$ q \ bar q g $状态产量的贡献,即高能在高能下深度弹性散射中的衍射横截面。获得的横截面是有限的,并且是衍射结构函数的完整临近领先顺序结果的一部分。我们在Eikonal限制中以精确的运动学进行计算,并表明先前已知的高$ Q^2 $和大型$ M_X^2 $结果可以从我们的结果中提取适当的限制。此外,我们讨论了为结构功能获得完整的临近领先顺序结果所需的步骤。
We calculate the contribution from the $q \bar q g$ state production to the diffractive cross sections in deep inelastic scattering at high energy. The obtained cross section is finite by itself and a part of the full next-to-leading order result for the diffractive structure functions. We perform the calculation in exact kinematics in the eikonal limit, and show that the previously known high-$Q^2$ and large $M_X^2$ results for the structure functions can be extracted from our results in the appropriate limits. We furthermore discuss the steps required to obtain the full next-to-leading order results for the structure functions.
