论文摘要
在LHC上，Gluon发起的过程被认为是Di-Higgs生产的主要来源。但是，在存在新的共鸣的情况下，轻快的启动过程也可以显着贡献。在本文中，我们查看了由新的Singlet标量介导的Di-Higgs生产。该单元是通过涉及标量leptoquark和右手中微子的环中的夸克 - 易夸克和Gluon融合过程产生的。通过Atlas合作的最新共鸣di-higgs搜索启发的基准参数，我们研究了在TEV范围内通过高亮度LHC（HL-LHC）在$ b \ bar {b} b}τ^{+}τ^{+bar {b}τ^{ - } fi Multy Mode a Multeriate分析的前景。我们获得了$5σ$和$2σ$轮廓，发现参数空间的很大一部分在HL-LHC的范围内。
At the LHC, the gluon-initiated processes are considered to be the primary source of di-Higgs production. However, in the presence of a new resonance, the light-quark initiated processes can also contribute significantly. In this paper, we look at the di-Higgs production mediated by a new singlet scalar. The singlet is produced in both quark-antiquark and gluon fusion processes through loops involving a scalar leptoquark and right-handed neutrinos. With benchmark parameters inspired from the recent resonant di-Higgs searches by the ATLAS collaboration, we examine the prospects of such a resonance in the TeV-range at the High-Luminosity LHC (HL-LHC) in the $b\bar{b} τ^{+}τ^{-}$ mode with a multivariate analysis. We obtain the $5σ$ and $2σ$ contours and find that a significant part of the parameter space is within the reach of the HL-LHC.
