Moyal空间上的非对易诱导规范理论

Noncommutative Induced Gauge Theories on Moyal Spaces

Jean-Christophe Wallet

摘要:

Moyal空间上的非对易场论可以在非对易几何的框架内方便地处理。简要回顾了几种现已确定的可重整物质场论。这些非对易Moyal空间,这仍然是一个具有挑战性的问题,可重整规范理论的建设,然后仔细检查。本文给出了在与外部规范势最小耦合的可重整化理论中,对标量场积分所产生的单圈有效规范理论的四维计算。规范不变的有效作用量被发现涉及,超出预期的纯杨-米尔斯作用量的非对易版本,额外的条款,可以解释为规范理论对应的调和项,这对于非对易$ϕ^4$ -理论在Moyal空间确保可重整性。提出并讨论了定义在Moyal空间上的一类可能的可重正化规范理论作用量。

英文摘要:

Noncommutative field theories on Moyal spaces can be conveniently handled within a framework of noncommutative geometry. Several renormalisable matter field theories that are now identified are briefly reviewed. The construction of renormalisable gauge theories on these noncommutative Moyal spaces, which remains so far a challenging problem, is then closely examined. The computation in 4-D of the one-loop effective gauge theory generated from the integration over a scalar field appearing in a renormalisable theory minimally coupled to an external gauge potential is presented. The gauge invariant effective action is found to involve, beyond the expected noncommutative version of the pure Yang-Mills action, additional terms that may be interpreted as the gauge theory counterpart of the harmonic term, which for the noncommutative $ϕ^4$-theory on Moyal space ensures renormalisability. A class of possible candidates for renormalisable gauge theory actions defined on Moyal space is presented and discussed.
