W. J. Stirling, E. Vryonidou, J. D. Wells

摘要:

我们在LHC和最近讨论的高能升级(HE LHC)计算transplanckian部分子散射在平坦的额外维理论。我们报告新的领先阶计算的QCD背景。我们采用适当的削减,以满足必要条件的程函近似是有效的,而在同一时间最大化的信号与背景比在大型强子对撞机的能量。我们研究的程函信号的可计算性,并考虑可能的33 TeV的高能量升级的LHC,这有助于扩展可计算的区域,并提高信号背景比的效果。

英文摘要:

We compute transplanckian parton scattering in flat extra-dimensional theories at the LHC and at the recently discussed high-energy upgrade (HE LHC). We report new leading-order calculations of the QCD background. We apply appropriate cuts to satisfy the necessary conditions for the eikonal approximation to be valid while at the same time maximising the signal to background ratio at LHC energies. We study the computability of the eikonal signal and consider the effect of a possible 33 TeV high-energy upgrade to the LHC, which serves to extend the calculable region and to enhance the signal to background ratio.
