论文摘要
在这项工作中，我们研究了具有全球连续$ r $对称性的最小超对称模型的颜色量表标量（SGLUON）的对撞机现象学。我们系统地分类了标量和伪尺度sgluons的重要衰减通道，并确定这些模型中自然的新型特征。这些包括在非标准的Diboson通道中的衰减，例如Gluon和Photon；三体腐烂，分支分数相当大；和带有顶点签名的长寿命颗粒。我们还讨论了这些粒子的单一和一对产生，并表明它们可以在合理参数空间的大区域中逃避从大型强子对撞机到变化的范围的现有约束。例如，我们发现在现实情况下仍然可以容纳725 GEV标量和350 GEV或较轻的伪cal。
In this work we study the collider phenomenology of color-octet scalars (sgluons) in minimal supersymmetric models endowed with a global continuous $R$ symmetry. We systematically catalog the significant decay channels of scalar and pseudoscalar sgluons and identify novel features that are natural in these models. These include decays in nonstandard diboson channels, such as to a gluon and a photon; three-body decays with considerable branching fractions; and long-lived particles with displaced vertex signatures. We also discuss the single and pair production of these particles and show that they can evade existing constraints from the Large Hadron Collider, to varying extents, in large regions of reasonable parameter space. We find, for instance, that a 725 GeV scalar and a 350 GeV or lighter pseudoscalar can still be accommodated in realistic scenarios.
