非阿贝尔张量规范场的粒子谱

Particle spectrum of Non-Abelian tensor gauge fields

George Savvidy

摘要:

简要回顾了非阿贝尔张量规范场理论,分析了当相互作用耦合常数趋于零时,低秩规范场的自由场方程。类似于电动力学和非阿贝尔规范理论,自由场方程用扩展场强张量的一阶导数表示。我们确定的自由场方程的粒子含量和计数的传播模式,他们描述。在四维时空中,秩为2的规范场描述了螺旋度为2和0的传播模。我们证明了秩为3的规范场描述了螺旋度为3的规范玻色子和螺旋度为1的规范玻色子的二重态的传播模。只有四维时空是物理上可接受的,因为在五维和更高维的时空中,方程的解具有负范数态。本文讨论了高阶规范场的粒子谱结构。

英文摘要:

We present a brief review of the non-Abelian tensor gauge field theory and analyze its free field equations for lower rank gauge fields when the interaction coupling constant tends to zero. The free field equations are written in terms of the first order derivatives of extended field strength tensors similar to the electrodynamics and non-Abelian gauge theories. We determine the particle content of the free field equations and count the propagating modes which they describe. In four-dimensional space-time the rank-2 gauge field describes propagating modes of helicity two and zero. We show that the rank-3 gauge field describes propagating modes of helicity-three and a doublet of helicity-one gauge bosons. Only four-dimensional space-time is physically acceptable, because in five- and higher-dimensional space-time the equation has solutions with negative norm states. We discuss the structure of the particle spectrum for higher rank gauge fields.
