标题： Light-flavor squark reconstruction at CLIC

摘要： 我们提出了一项模拟研究，探讨了在基于CLIC技术的3 TeV e+e-对撞机上测量TeV尺度轻味右旋夸克质量的可能性。 在所考虑的模型中，这些粒子衰变为它们的标准模型对应粒子和最轻的中性子，产生两个喷注加上缺失能量的信号。 该分析基于CLIC_ILD探测器概念的完整GEANT4模拟，包括标准模型物理背景以及来自双光子过程的束流诱导强子背景。 该分析作为在具有显著缺失能量事件中高能喷注重建的通用基准。 评估了几种喷注寻找算法，其中纵向不变kt算法在面对束流诱导背景时表现出高度的鲁棒性，同时保留了通常在用于e+e-碰撞的算法中发现的特征。 所提出的轻味超夸克重建研究显示，对于TeV尺度的超夸克质量，在CLIC上可以实现百分之一以下的精度进行质量测量。 显示英文摘要

摘要： We present a simulation study of the prospects for the mass measurement of TeV-scale light-flavored right-handed squarks at a 3 TeV e+e- collider based on CLIC technology. In the considered model, these particles decay into their standard-model counterparts and the lightest neutralino, resulting in a signature of two jets plus missing energy. The analysis is based on full GEANT4 simulations of the CLIC_ILD detector concept, including Standard Model physics backgrounds and beam-induced hadronic backgrounds from two-photon processes. The analysis serves as a generic benchmark for the reconstruction of highly energetic jets in events with substantial missing energy. Several jet finding algorithms were evaluated, with the longitudinally invariant kt algorithm showing a high degree of robustness towards beam-induced background while preserving the features typically found in algorithms developed for e+e- collisions. The presented study of the reconstruction of light-flavored squarks shows that for TeV-scale squark masses, sub-percent accuracy on the mass measurement can be achieved at CLIC.
