引力、规范场和希格斯玻色子的统一
Unification of gravity, gauge fields, and Higgs bosons
摘要：
本文研究了一个规范场的自同态不变量理论，该规范场取值于一个自发破缺为时空Lorentz代数、一个Yang-Mills代数及其补代数的直和的李代数。从一个完全规范不变的行动-一个广义相对论的普列班斯基行动的扩展-我们恢复重力，杨米尔斯和希格斯场的行动。对称破缺后得到的低能耦合常数都是初始作用量中的单参数和希格斯粒子真空期望值的函数。
英文摘要：
We consider a diffeomorphism invariant theory of a gauge field valued in a Lie algebra that breaks spontaneously to the direct sum of the spacetime Lorentz algebra, a Yang-Mills algebra, and their complement. Beginning with a fully gauge invariant action -- an extension of the Plebanski action for general relativity -- we recover the action for gravity, Yang-Mills, and Higgs fields. The low-energy coupling constants, obtained after symmetry breaking, are all functions of the single parameter present in the initial action and the vacuum expectation value of the Higgs.
