标题： UV Completed Composite Higgs model with heavy composite partners

摘要： 我们研究在具有纯费米子紫外完成的最小复合希格斯模型$SU(4)/Sp(4)$中的电弱对称性破缺，这些完成基于一个束缚的超色规范群，并发现来自基础前子质量的额外希格斯势能会破坏希格斯粒子质量与复合伙伴之间的关联。因此，为了成功实现电弱对称性破缺，复合伙伴可以非常重，而无需增强新物理尺度与希格斯真空期望值之间的分离。因此，这种模型可以通过普通的强相互作用理论轻松实现，而无需人为假设，并且更可能与格点模拟一致。部分复合性的紫外完成预测了一个轻的单态戈德斯通玻色子，它通过威斯-祖姆ino-维滕项与QCD和电弱规范玻色子相互作用。它可以在大型强子对撞机上通过胶子融合产生并衰变为规范玻色子对。我们简要讨论了其现象学并推导了其来自大型强子对撞机搜索的限制。 显示英文摘要

摘要： We study electroweak symmetry breaking in minimal composite Higgs models $SU(4)/Sp(4)$ with purely fermionic UV completions based on a confining Hypercolor gauge group and find that the extra Higgs potential from the underlying preon mass can destruct the correlation between the mass of Higgs and composite partners. Thus the composite partners can be very heavy for successful electroweak symmetry breaking without enhancing the separation between the new physical scale and Higgs VEV. So this kind of model can be easily realized by ordinary strong dynamics theories without artificial assumptions and more likely consistent with lattice simulations. The UV completion of partial compositeness predicts a light singlet Goldstone boson which interacts with QCD and electroweak gauge bosons through Wess-Zumino-Witten terms. It can be produced through gluon fusion at LHC and decay into gauge boson pairs. We briefly discuss its phenomenology and derive its bounds from LHC searches.
