论文摘要
我们研究了强烈耦合的，大约规模不变的仪表理论，这些理论在红外线中产生了质量差距。我们认为，大量的费米风味最适合为复合材料Higgs场景提供紫外线完成。全息方法允许描述委内斯诺限制中非扰动动力学的定性特征。我们介绍了新的自下而上全息模型，该模型结合了几何形状上的风味，并表明这可以将质量差距与风味对称性破坏的规模相关联。我们计算了各种复合骨骼状态的质谱，并研究了其对对称性操作员的缩放维度以及口味数量的依赖性。对带有光dialaton的不同区域进行了严格的调查。我们仔细评估了全息方法的有效性领域，并将其与晶格模拟和Nambu-Jona-Lasinio模型进行了比较。
We study strongly-coupled, approximately scale-invariant gauge theories, which develop a mass gap in the infrared. We argue that a large number of fermion flavours is most suitable to provide an ultraviolet completion for the composite Higgs scenario. The holographic approach allows to describe the qualitative features of the non-perturbative dynamics in the Veneziano limit. We introduce new bottom-up holographic models, which incorporate the backreaction of flavour on the geometry, and show that this can correlate the mass gap to the scale of flavour-symmetry breaking. We compute the mass spectrum for the various composite bosonic states, and study its dependence on the scaling dimension of the symmetry-breaking operators, as well as on the number of flavours. The different regions with a light dilaton are critically surveyed. We carefully assess the domain of validity of the holographic approach, and compare it with lattice simulations and the Nambu--Jona-Lasinio model.
