论文摘要
提出了沿LHC梁1（顺时针方向）在LHCB相互作用点（IP8）附近的质子轨迹，以最新的LHC运行4光学（HLLHC1.5）。在此基础上，确定了前向质子检测器的三个可能位置：距IP8的150、180和430 m。对于这些位置，估计了几何接受。对于质子的相对能量损失，$ξ$，这些限制为$ 0.05 <ξ\ Lessim 0.1 $，$ 0.025 <ξ\ sillsim 0.1 $和$ 0.003 <ξ<0.013 $。讨论了由于接受LHCB探测器对$ξ$的接受而导致的中央系统的影响。最后，提出了堆积的影响。
Proton trajectories along LHC beam 1 (clockwise direction) in the vicinity of the LHCb Interaction Point (IP8) for the most recent LHC Run 4 optics (HLLHC1.5) were presented. On this basis, three possible locations of forward proton detectors were identified: 150, 180 and 430 m from IP8. For these locations geometric acceptances were estimated. For the proton relative energy loss, $ξ$, these limits are $0.05 < ξ\lesssim 0.1$, $0.025 < ξ\lesssim 0.1$ and $0.003 < ξ< 0.013$, respectively. The influence of boost of the central system due to the acceptance of LHCb detector on $ξ$ was discussed. Finally, the impact of pile-up was presented.
