In this paper, we explore the signature of a simplified model which includes a new singlet scalar state and a vector like quark at future lepton colliders. In particular, we study the production of the new singlet scalar in association with a photon, which proceeds through loop level diagrams involving a vector like top quark partner, at future e − e + colliders with different center-of-mass energies from 500 GeV to 3 TeV. To show the sensitivity of the process, the exclusion limits on the parameter space of the model are presented considering the decay of the singlet scalar into a pair of Higgs bosons, followed by the decay of Higgs bosons into ##IMG## [http://ej.iop.org/images/0954-3899/47/7/075004/jpgab772fieqn1.gif] {$b\bar{b}$} pairs. The results are compared to those obtained from the LHC, electroweak precision data and other channels at lepton colliders and it is shown that a notable sensitivity to the parameter sp...

在未来的轻子对撞机上像顶夸克一样通过矢量循环诱导单重态标量生产

在本文中，我们探索了简化模型的签名，该模型包括一个新的单重态标量状态和一个类似未来的轻子对撞机上的夸克这样的向量。特别是，我们研究了与光子相关联的新单重态标量的产生，该过程通过循环级图进行，该循环级图涉及诸如顶夸克伴侣之类的矢量，在未来的e-e +对撞机中具有不同质心能量（从500 GeV开始）至3 TeV。为了说明该过程的敏感性，考虑到单重标量向一对希格斯玻色子的衰减，接着是希格斯玻色子向## IMG ##的衰减，提出了模型参数空间的排除极限。 //ej.iop.org/images/0954-3899/47/7/075004/jpgab772fieqn1.gif] {$ b \ bar {b} $}对。将结果与从大型强子对撞机获得的结果进行比较，
