Title: 视角的转变：在CMS和ATLAS中观测中微子

Abstract: We investigate the physics potential of SHIFT@LHC, a proposed gaseous fixed target installed in the LHC tunnel, as a novel source of detectable neutrinos. Using simulations of proton-gas collisions, hadron propagation, and neutrino interactions, we estimate that $O(10^4)$ muon-neutrino and $O(10^3)$ electron-neutrino interactions, spanning energies from 20 GeV to 1 TeV, would occur in the CMS and ATLAS detectors with 1% of the LHC Run-4 integrated luminosity. This unique configuration provides access to hadron production in the pseudorapidity range 5<$\eta$<8, complementary to existing LHC detectors. If realized, this would mark the first detection of neutrinos in a general-purpose LHC detector, opening a new avenue to study neutrino production and interactions in a regime directly relevant to atmospheric neutrino experiments.

Abstract: 我们研究了SHIFT@LHC的物理潜力，这是一个拟议的气体固定靶，安装在LHC隧道中，作为可探测中微子的新来源。 通过质子-气体碰撞、强子传播和中微子相互作用的模拟，我们估计，在1%的LHC Run-4积分亮度下，CMS和ATLAS探测器中将发生$O(10^4)$个μ子中微子和$O(10^3)$个电子中微子相互作用，能量范围从20 GeV到1 TeV。 这种独特的配置提供了对赝快度范围5<$\eta$<8内的强子产生进行研究的机会，这与现有的LHC探测器形成补充。 如果实现，这将是通用型LHC探测器中首次检测到中微子，为研究与大气中微子实验直接相关的中微子产生和相互作用开辟了一条新途径。
