NLO QCD对引力子诱导的深度非弹性散射的修正

NLO QCD Corrections to Graviton Induced Deep Inelastic Scattering

W. J. Stirling, E. Vryonidou

摘要:

我们考虑了与深度非弹性散射实验相关的次首阶QCD修正。我们通过计算一组引力子相互作用图的虚和实修正来计算相关的非线性光学结构函数,证明了紫外和红外发散的预期消除。我们比较了NLO和LO的结果,在中心的质量能量相关的HERA实验,以及拟议的更高能量的轻子质子对撞机,LHeC,它具有更高的基本规模达到。

英文摘要:

We consider Next-to-Leading-Order QCD corrections to ADD graviton exchange relevant for Deep Inelastic Scattering experiments. We calculate the relevant NLO structure functions by calculating the virtual and real corrections for a set of graviton interaction diagrams, demonstrating the expected cancellation of the UV and IR divergences. We compare the NLO and LO results at the centre-of-mass energy relevant to HERA experiments as well as for the proposed higher energy lepton-proton collider, LHeC, which has a higher fundamental scale reach.
