Abstract

By extracting the beam with a bent crystal or by using an internal gas target, the multi-TeV proton and lead LHC beams allow one to perform the most energetic fixed-target experiments (AFTER@LHC) and to study $p$+$p$ and $p$+A collisions at $\sqrt{s_{NN}}$=115 GeV and Pb+$p$ and Pb+A collisions at $\sqrt{s_{NN}}$=72 GeV. Such studies would address open questions in the domain of the nucleon and nucleus partonic structure at high-$x$, quark-gluon plasma and, by using longitudinally or transversally polarised targets, spin physics. In this paper, we discuss the physics opportunities of a fixed-target experiment at the LHC and we report on the possible technical implementations of a high-luminosity experiment. We finally present feasibility studies for Drell-Yan, open heavy-flavour and quarkonium production, with an emphasis on high-$x$ and spin physics.

大型强子对撞机固定目标实验的物理机会(AFTER@LHC)

通过使用弯曲晶体或使用内部气体靶提取光束，多tev质子和铅LHC光束允许人们进行最高能量的固定目标实验(AFTER@LHC)，并研究$\sqrt{s_{NN}}$=115 GeV的$p$+$p$和$p$+ a碰撞和$\sqrt{s_{NN}}$=72 GeV的Pb+$p$和Pb+ a碰撞。这样的研究将解决高x射线下的核子和核子部分子结构、夸克-胶子等离子体以及使用纵向或横向极化目标的自旋物理学等领域的开放性问题。在本文中，我们讨论了在大型强子对撞机上进行固定目标实验的物理机会，并报告了高亮度实验的可能技术实现。最后，我们提出了Drell-Yan、open heavy- flavor和quarkonium生产的可行性研究，重点是高x值和自旋物理。
