强相互作用动力学和在LHC上寻找新物理
Strongly interacting dynamics and the search for new physics at the LHC
摘要：
本文给出了在基本表象下含$N_f = 8$轻费米子的强相互作用SU（3）规范理论的谱。进行非微扰晶格计算在最轻的质量和最大的体积考虑到目前为止，我们确认存在一个显着的光单重标量粒子。我们在大型强子对撞机（LHC）上寻找标准模型之外的新物理的背景下，探索了8味理论的丰富共振谱。将我们的结果与动态电弱对称性破缺模型相连接，我们估计矢量共振质量约为2 TeV，宽度约为450 GeV，并预测质量低于3 TeV的额外共振。
英文摘要：
We present results for the spectrum of a strongly interacting SU(3) gauge theory with $N_f = 8$ light fermions in the fundamental representation. Carrying out non-perturbative lattice calculations at the lightest masses and largest volumes considered to date, we confirm the existence of a remarkably light singlet scalar particle. We explore the rich resonance spectrum of the 8-flavor theory in the context of the search for new physics beyond the standard model at the Large Hadron Collider (LHC). Connecting our results to models of dynamical electroweak symmetry breaking, we estimate the vector resonance mass to be about 2 TeV with a width of roughly 450 GeV, and predict additional resonances with masses below ~3 TeV.
