翻滚到顶端

Tumbling to the Top

Giacomo Cacciapaglia, Shahram Vatani, Zhi-Wei Wang

摘要:

我们提出了一种新的机制来产生的耦合的顶夸克的复合戈德斯通希格斯,我们称之为{ \it全球扩展Technicolor}(GETC)。上图中,技术费米子和自旋为1的介体作为翻滚的手征规范理论的束缚态出现。我们提出了一个简单的模型的基础上翻滚的$SU(4)$动力学,它预测部分复合顶部和$SU(3)$模型与6狄拉克风味的低能量复合希格斯。中子衰变边界要求新的动力学限制在$10^{6÷7}$ TeV以上。基本模型的简单扩展还允许生成bottom和tau的部分复合性,以及来自具有10种风味(6种轻+ 4种重)的中间$SU(3)$理论的行走动力学,其动力学可以在晶格上研究。

英文摘要:

We propose a new mechanism to generate the couplings of the top quark to a composite Goldstone Higgs, which we dub {\it Global Extended Technicolor} (GETC). Top, techni-fermions and spin-1 mediators arise as bound states of a tumbling chiral gauge theory. We propose a simple model based on a tumbling $SU(4)$ dynamics, which predicts partial compositeness for the top and an $SU(3)$ model with 6 Dirac flavours for the low-energy composite Higgs. Neutron decay bounds require the new dynamics to confine above $10^{6÷7}$ TeV. A simple extension of the basic model allows to generate partial compositeness also for bottom and tau, and a walking dynamics from an intermediate $SU(3)$ theory with 10 flavours (6 light + 4 heavy), whose dynamics can be studied on the Lattice.
