论文摘要
超出标准模型场景以外的许多引人注目的信号会导致非常规带电的粒子轨迹。异常轨道的签名是该事件最显着的特征，这对大型强子对撞机（LHC）的实验构成了重大挑战，特别是对于触发器。本文对即将到来的高光度LHC的一组代表性的长寿和非常规签名的基于轨道的触发器进行了研究，并为基于硬件的跟踪系统的目标参数提出了建议。所研究的场景包括在软能能源模型中产生的大量低动量轨道，流离失所的瘦素和异常的及时轨道在具有长期寿命的Suppersymmememmememmetry模型中预测的，并具有长期的HIGGS Portal Portal Sportal Scalars Portal Spotal sceman中预测的放置HADRON。
Many compelling beyond the Standard Model scenarios predict signals that result in unconventional charged particle trajectories. Signatures for which unusual tracks are the most conspicuous feature of the event pose significant challenges for experiments at the Large Hadron Collider (LHC), particularly for the trigger. This article presents a study of track-based triggers for a representative set of long-lived and unconventional signatures at the upcoming High Luminosity LHC, as well as resulting recommendations for the target parameters of a hardware-based tracking system. Scenarios studied include large multiplicities of low momentum tracks produced in a soft-unclustered-energy-pattern model, displaced leptons and anomalous prompt tracks predicted in a Supersymmetry model with long-lived staus, and displaced hadrons predicted in a Higgs portal scenario with long-lived scalars.
