摘要:

本文介绍了30年代在LHC上进行的一个发光的、能量前沿的电子-强子($eh$)散射实验的物理、装置和加速器设计的新设想,讨论了其中的关键物理问题及其与强子-强子HL-LHC物理计划的关系。这些物理课题对LHeC探测器的设计提出了新的要求,并对LHeC探测器的设计提出了相应的改进。加速器的设计,特别是相互作用区(IR)的优化。最初的加速器考虑表明,有可能建立一个共同的IR,它可以交替地服务于$eh$和$hh$碰撞,而其他实验将停留在$hh$上。的LHeC探测器的一个向前向后对称的选择勾勒出这将允许扩展LHeC物理方案,也包括强子-强子物理方面。联合$eh$和$hh$物理实验的愿景被证明为解决高能重离子物理的基本问题,包括原子核的部分子结构和流体力学的出现在量子场论,而真正的TeV尺度DIS物理是前所未有的级别打开了新的前景。

英文摘要:

Novel considerations are presented on the physics, apparatus and accelerator designs for a future, luminous, energy frontier electron-hadron ($eh$) scattering experiment at the LHC in the thirties for which key physics topics and their relation to the hadron-hadron HL-LHC physics programme are discussed. Demands are derived set by these physics topics on the design of the LHeC detector, a corresponding update of which is described. Optimisations on the accelerator design, especially the interaction region (IR), are presented. Initial accelerator considerations indicate that a common IR is possible to be built which alternately could serve $eh$ and $hh$ collisions while other experiments would stay on $hh$ in either condition. A forward-backward symmetrised option of the LHeC detector is sketched which would permit extending the LHeC physics programme to also include aspects of hadron-hadron physics. The vision of a joint $eh$ and $hh$ physics experiment is shown to open new prospects for solving fundamental problems of high energy heavy-ion physics including the partonic structure of nuclei and the emergence of hydrodynamics in quantum field theory while the genuine TeV scale DIS physics is of unprecedented rank.
