具有协变星积的规范场理论

Gauge field theories with covariant star-product

M. Chaichian, A. Tureanu, G. Zet

摘要:

利用定义在辛流形上的微分形式之间的协变星积,发展了一个非对易的规范理论。证明了场强二形式是规范协变的,并且满足变形的Bianchi恒等式。利用时空上的规范协变度量定义了非对易的杨-米尔斯作用量,证明了其在非对易参数下的规范不变性直到二阶。

英文摘要:

A noncommutative gauge theory is developed using a covariant star-product between differential forms defined on a symplectic manifold, considered as the space-time. It is proven that the field strength two-form is gauge covariant and satisfies a deformed Bianchi identity. The noncommutative Yang-Mills action is defined using a gauge covariant metric on the space-time and its gauge invariance is proven up to the second order in the noncommutativity parameter.
