论文摘要
我们通过$ b-l $ $ $ z'$ boson和LHC（HL-LHC）的高光度运行和未来的$ PP $ Collider（FCC-HH）研究了右撇子中微子（RHNS）的成对生产。我们专注于$ 10-70 $ GEV的RHN状态，这自然会导致流离失所的顶点，以实现小小的活动性混合强度。通过$ m_ {z'} \ ge 1 $ tev产生的，rhns大大提高，导致直接的衰减产品产生脂肪的喷射。我们研究了内部检测器和哑光光谱仪中专用特征的检测前景，分别是一对流离失所的脂肪射流和相关的轨道。我们发现，HL-LHC和FCC-HH都可以对小型活动混合$ v_ {μn}> 10^{ - 6} $和$ v_ {μn}> 10^{ - 7} $，其中的事件数量达到$ \ \ \ \ \ \ \ \} $和$ \ \ \ 10^333333.33333333333333333333）这允许在这种情况下通过Seesaw机制探测光中微子质量的产生。
We investigate the pair-production of Right-Handed Neutrinos (RHNs) via a $B-L$ $Z'$ boson and the detection prospects at the High-Luminosity run of the LHC (HL-LHC) and a future $pp$ collider (FCC-hh). We focus on RHN states with a mass of $10-70$ GeV which naturally results in displaced vertices for small active-sterile mixing strengths. Being produced through a mass resonance with $m_{Z'} \ge 1$ TeV, the RHNs are heavily boosted, leading to collimated decay products that give rise to fat-jets. We investigate the detection prospect of dedicated signatures in the inner detector and the muon spectrometer, namely a pair of displaced fat-jets and the associated tracks, respectively. We find that both the HL-LHC and FCC-hh can be sensitive to small active-sterile mixing $V_{μN} > 10^{-6}$ and $V_{μN} > 10^{-7}$ with the number of events reaching $\mathcal{O}(10)$ and $\mathcal{O}(10^3)$, respectively. This allows probing the generation of light neutrino masses through the Seesaw mechanism in this scenario.
