我们考虑了在TeV尺度下具有额外中性规范玻色子z '的一类标准模型的最小阿贝尔扩展。在这些情况下,一个扩展的标量扇区和重右手中微子自然会被设想出来。我们在大型强子对撞机上展示了它们的一些引人注目的特征,其中最有趣的是aZ衰变为重中微子对,以及一个重标量衰变为两个标准模型希格斯玻色子。使用重整化群方法,我们描述了这些扩展的高能行为,并利用嵌入到更广泛的GUT场景中所施加的约束。
We consider a class of minimal abelian extensions of the Standard Model with an extra neutral gauge bosonZ′ at the TeV scale. In these scenarios an extended scalar sector and heavy right-handed neutrinos are naturally envisaged. We present some of their striking signatures at the Large Hadron Collider, the most interesting arising from aZ′ decaying to heavy neutrino pairs as well as a heavy scalar decaying to two Standard Model Higgses. Using renormalisation group methods, we characterise the high energy behaviours of these extensions and exploit the constraints imposed by the embedding into a wider GUT scenario.
