第四族的双夸克

Diquarks from a fourth family

Bob Holdom

摘要:

如果第四族凝聚是导致电弱对称破缺的原因,那么它们也可能破缺近似的整体对称。在由此产生的伪戈德斯通玻色子中,有一些可以具有双夸克量子数。我们描述了各种双夸克和它们的衰变模式,我们发现方面是特定的第四家庭的框架。壮观的签名在大型强子对撞机上出现,并探讨了600 GeV质量的彩色六重体双夸克。我们考虑一个简单的搜索策略,避免双夸克重建。我们还考虑350 GeV的质量双夸克,可在Tevatron。

英文摘要:

If fourth family condensates are responsible for electroweak symmetry breaking then they may also break approximate global symmetries. Among the resulting pseudo-Goldstone bosons are those that can have diquark quantum numbers. We describe the variety of diquarks and their decay modes, and we find aspects that are particular to the fourth family framework. Spectacular signatures at the LHC appear and are explored for color sextet diquarks with 600 GeV mass. We consider a simple search strategy which avoids diquark reconstruction. We also consider 350 GeV mass diquarks that are accessible at the Tevatron.
