LHC早期发现重色向量的新策略

A New Strategy to Discover Heavy Colored Vectors at the Early LHC

Natascia Vignaroli

摘要:

我们进行了研究的LHC发现达到重胶子(G*)和重费米子(顶部和底部的激发),来自一个新的复合部门。我们发现重费米子共振对复合胶子现象有很大的影响。如果复合胶子比复合费米子重,就像味观测值所暗示的那样,那么在G* 衰变成重费米子及其标准模型伙伴的通道中的搜索是非常有希望的,有可能在LHC的早期发现G* 和重费米子。该通道还提供了提取关于模型参数的重要信息的可能性,例如最高复合度。

英文摘要:

We perform a study of the LHC discovery reach on a heavy gluon (G*) and heavy fermions (top and bottom excitations), coming from a new composite sector. We find that heavy fermion resonances have a great impact on the composite gluon phenomenology. If the composite gluon is heavier than composite fermions, as flavor observables seem to suggest, the search in the channel where G* decays into a heavy fermion plus its Standard Model partner is very promising, with the possibility for both the G* and heavy fermions to be discovered at the early stage of the LHC. The channel offers also the possibility to extract important information on model parameters, such as the top degree of compositeness.
