四维规范理论中的拓扑质量产生

Topological mass generation in four-dimensional gauge theory

George Savvidy

摘要:

非阿贝尔张量规范场的拉格朗日量描述了杨-米尔斯玻色子和螺旋度增加的无质量张量玻色子的相互作用。我们发现了一个与度规无关的规范不变密度,它是Chern-Simons密度的四维模拟。由这种类似陈-西蒙斯不变量扩充的拉格朗日量描述了大质量的杨-米尔斯玻色子,为四维规范场理论提供了规范不变的质量间隙。我们提出的不变密度,可以提供质量的高阶张量玻色子。

英文摘要:

The Lagrangian of non-Abelian tensor gauge fields describes the interaction of the Yang-Mills and massless tensor bosons of increasing helicities. We have found a metric-independent gauge invariant density which is a four-dimensional analog of the Chern-Simons density. The Lagrangian augmented by this Chern-Simons-like invariant describes massive Yang-Mills boson, providing a gauge-invariant mass gap for a four-dimensional gauge field theory. We present invariant densities which can provide masses to the high rank tensor bosons.
