标题： Composite Higgs scenario in mass-split models

摘要： 质量分裂复合希格斯模型自然地解释了观测到的125 GeV轻希格斯玻色子，并预测了与其他较重共振态之间的较大能标分离。 我们通过数值模拟研究了具有四个轻（无质量）和六个重（有质量）味的SU(3)规范系统。由于底层系统具有退化且无质量的十味似乎表现出红外共形性，此系统继承了共形超尺度性质，允许研究近共形动力学。 通过非微扰格点场论模拟，我们给出了低能粒子谱。我们展示了超尺度特性，预测了对应共形不动点的异常质量维度，并表明在所研究的质量范围内，数据可以用膨胀的手征微扰理论来描述。 接近共形红外不动点的存在导致了高度可预测的粒子谱，这与量子色动力学（QCD）有很大的不同。此外，我们还展示了有限温度下初始的研究结果。 显示英文摘要

摘要： Mass-split composite Higgs models naturally accommodate the experimental observation of a light 125 GeV Higgs boson and predict a large scale separation to other heavier resonances. We explore the SU(3) gauge system with four light (massless) and six heavy (massive) flavors by performing numerical simulations. Since the underlying system with degenerate and massless ten flavors appears to be infrared conformal, this system inherits conformal hyperscaling and allows to study near-conformal dynamics. Carrying out nonperturbative lattice field theory simulations, we present the low-lying particle spectrum. We demonstrate hyperscaling, predict the anomalous mass dimension of the corresponding conformal fixed point, and show that in the investigated mass regime the data are described by dilaton chiral perturbation theory. The proximity of a conformal infrared fixed point leads to a highly predictive particle spectrum which is quite distinct from QCD. Further we present initial results of our finite temperature investigations.
