论文摘要
LHC的中微子物理计划很快将由FASER实验启动，它将为中微子相互作用顶点的精确研究提供独特的机会。这还将为在特定的高能中微子束 - 降低实验中在此类相互作用中产生的标准模型（BSM）颗粒以外搜索的可能性。在这项研究中，我们说明了使用偶极子或$ z^\ prime $ portal到GEV规模重型中性瘦素的模型中进行此类搜索的前景。为此，我们既采用了新物理学的标准签名，这些标准签名由衰减容器中出现的一对相对充满电的曲目和其他类型的搜索组成。这些包括高能光子和单个散射电子。我们表明，在LHC的高光度阶段，这种多种实验特征可以显着扩展未来多用途Faser 2检测器的灵敏度覆盖率。
The neutrino physics program at the LHC, which will soon be initiated by the FASER experiment, will provide unique opportunities for precision studies of neutrino interaction vertices at high energies. This will also open up the possibility to search for beyond the standard model (BSM) particles produced in such interactions in the specific high-energy neutrino beam-dump experiment. In this study, we illustrate the prospects for such searches in models with the dipole or $Z^\prime$ portal to GeV-scale heavy neutral leptons. To this end, we employ both the standard signature of new physics that consists of a pair of oppositely-charged tracks appearing in the decay vessel, and the additional types of searches. These include high-energy photons and single scattered electrons. We show that such a variety of experimental signatures could significantly extend the sensitivity reach of the future multi-purpose FASER 2 detector during the High-Luminosity phase of the LHC.
