标题： Mixed gluinos and sgluons from a new SU(3) gauge group

摘要： 我研究超对称模型，其中QCD规范群是从一个$SU(3) \times SU(3)$规范群在多TeV尺度的自发对称破缺中残留下来的对角子群。 在具有软超对称破缺的可重整化模型中，标量势被证明具有所需的规范对称破缺模式的全局极小值。 除了一个质量色八重态矢量玻色子外，这个框架预测了3个色八重态自旋为0的sgluon，以及4个带有狄拉克和马约拉纳质量项的色八重态gluino。 其中一个gluino质量本征态与夸克-平方夸克对的耦合至少和最小超对称理论的预测一样大，但它不一定是最轻的那个。 显示英文摘要

摘要： I study supersymmetric models in which the QCD gauge group is the remnant diagonal subgroup from the spontaneous breaking of an $SU(3) \times SU(3)$ gauge group at a multi-TeV scale. In renormalizable models with soft supersymmetry breaking, the scalar potential is shown to have global minima with the required gauge symmetry breaking pattern. In addition to a massive color octet vector boson, this framework predicts 3 color octet spin-0 sgluons, and 4 color octet gluinos with both Dirac and Majorana mass terms. One of the gluino mass eigenstates typically has a coupling to quark-squark pairs that is at least as large as the prediction of minimal supersymmetry, but it need not be the lightest one.
