论文摘要
我们提出了一个受扰动单位性要求约束的类似向量的夸克（VLQ）模型。在这种情况下，新的重VLQ与Sm夸克和玻色子的中性和充电耦合是严格相关的。我们得出相应的总和规则，并显示耦合的确定结构。我们在定性上分析了该模型的现象学后果，以预期宽度，生产机制和衰减通道。我们表明，即将到来的LHC运行3可能对此类粒子具有敏感性，但是应适应搜索策略，以覆盖主要在带电的通道t（b） - > wq中衰减的宽谐振。
We propose a Vector-like quark (VLQ) model constrained by the requirement of perturbative unitarity. In this scenario, the neutral and charged couplings of the new heavy VLQs to SM quarks and bosons are strictly related. We derive the corresponding sum rules and display the definite structure of the couplings. We analyse, qualitatively, the phenomenological consequences of this model in terms of expected width, production mechanism and decay channels. We show that the upcoming LHC run 3 could have sensitivity to such particles but the search strategy should be adapted to cover wide resonances decaying mainly in the charged channel T(B) -> Wq.
