格子上的共形窗

The conformal window on the lattice

Luigi Del Debbio

摘要:

晶格模拟可以在研究动态电弱对称性破缺中发挥重要作用,它可以提供候选理论的非微扰动力学的定量结果。对于这个计划的成功,它是至关重要的,以确定与现象学相关的问题,并开发工具,将提供这些问题的强有力的答案。非超对称规范理论的共形窗的存在性及其刻画是在格点上研究的重要唯象问题之一。本文总结了近年来红外不动点的数值模拟研究成果,讨论了它们的局限性,并分析了未来的发展方向。

英文摘要:

Lattice simulations can play an important role in the study of dynamical electroweak symmetry breaking by providing quantitative results on the nonperturbative dynamics of candidate theories. For this programme to succeed, it is crucial to identify the questions that are relevant for phenomenology, and develop the tools that will provide robust answers to these questions. The existence of a conformal window for nonsupersymmetric gauge theories, and its characterization, is one of the phenomenologically important problems that can be studied on the lattice. We summarize the recent results from studies of IR fixed points by numerical simulations, discuss their current limitations, and analyze the future perspectives.
