论文摘要
本文专用于标准模型横截面，用于生产单个顶部，成对的顶部夸克，三层夸克和四个在三个不同的质量元素中心，例如$ \ sqrt {s} = $ \ sqrt {s} = $ 7、10和14 tev在现有粒子界面以及未来的hadron colliders和未来的colliders colders。在标准模型背景的情况下，对三层夸克进行了全面的运动分析，以及对三层生产过程的顶级夸克的不变质量重建。这三个信号过程被迫以完全的辐射模式衰减，其意义是在$ \ sqrt {s} = $ 14 TEV的高光度大型强子对撞机（hl $ - $ lhc）中计算的，也以$ \ sqrt = $ \ sqrt {$ \ sqrt {s} = $ {s} = 27 tev。发现HL $ - $ LHC的可观察性并不是那么容易，而且机会要低得多，但有更高的机会观察he $ $ lhc的信号事件。估计所有信号和背景过程的信号与背景比率和信号意义，分别估计HL $ -LHC和He $ -LHC分别分别为$ \ sqrt {s} $ = 14 TEV和$ \ sqrt {s} $ = 27 tev。
This paper is devoted to the Standard Model cross-sections for the production of single top, top quark in pairs, triple-top quarks, and four top-quarks at three different centre of mass-energies e.g., $\sqrt{s}=$7, 10 and 14 TeV at existing particle colliders as well as at Future Hadron Colliders. A fully kinemtaic analysis with the optimized pre-selection cuts along with invariant mass reconstruction of top quarks is performed for triple-top production processes pp$\rightarrow $tttW, tttd,tttb in the presence of Standard Model background. The three signal processes are forced to decay in fully hadronic mode and their significance is computed in High Luminosity Large Hadron Collider (HL$-$LHC) at $\sqrt{s}=$14 TeV and also in High-Energy LHC (HE$-$LHC) at $\sqrt{s}=$27 TeV. It is found that the observability at HL$-$LHC will would not be so easy task and chances are much lower but there are higher chances to observe the signal events at HE$-$LHC. The signal to background ratio and signal significance of all signal and background processes are estimated for both the HL$-$LHC and the HE$-$LHC at $\sqrt{s}$ =14 TeV and $\sqrt{s}$ =27 TeV respectively.
