在SND @ LHC为新物理学做讲座

Searches for new physics at SND@LHC

Alexey Boyarsky, Oleksii Mikulenko, Maksym Ovchynnikov, Lesya Shchutska

摘要:

SND@LHC是一个被批准的实验,用于探测LHC中产生的中微子的远向散射,并旨在测量它们的性质。此外,该探测器还具有寻找可能在质子-质子碰撞中产生的新的弱相互作用粒子(FIPs)的潜力。在本文中,我们讨论FIPs签名SND@LHC考虑两类粒子:稳定的FIPs,可以通过它们的散射检测到,和不稳定的FIPs内的检测器衰减。我们估计SND@LHC探测疏光暗物质散射的灵敏度,并检测中微子,标量和矢量门户粒子的衰变。最后,我们还比较和定性分析了SND@LHC和FASER/FASERν实验在这些搜索中的潜力。

英文摘要:

SND@LHC is an approved experiment equipped to detect scattering of neutrinos produced in the far-forward direction at the LHC, and aimed to measure their properties. In addition, the detector has a potential to search for new feebly interacting particles (FIPs) that may be produced in proton-proton collisions. In this paper, we discuss FIPs signatures at SND@LHC considering two classes of particles: stable FIPs that may be detected via their scattering, and unstable FIPs that decay inside the detector. We estimate the sensitivity of SND@LHC to probe scattering of leptophobic dark matter, and to detect decays of neutrino, scalar, and vector portal particles. Finally, we also compare and qualitatively analyze the potential of SND@LHC and FASER/FASERν experiments for these searches.
