Grosse-Wulkenhaar模型的世界线方法

Worldline approach to the Grosse-Wulkenhaar model

Sebastián Franchino Viñas, Pablo Pisani

摘要:

将世界线理论应用于Grosse-Wulkenhaar模型,得到了单圈有效作用量的表达式,为计算该理论中的Schwinger函数提供了一种有效的方法.利用这个表达式,我们得到了对有效背景和$β$ -函数的量子修正,这些函数在自对偶点处为零。退化的非交换性的情况下,也被认为是。我们的主要结果可以直接应用到任何多项式自相互作用的标量场,我们认为,世界线的方法可能是有用的研究有效的行动,非对易规范场以及在其他非局部模型或在高导数场论。

英文摘要:

We apply the worldline formalism to the Grosse-Wulkenhaar model and obtain an expression for the one-loop effective action which provides an efficient way for computing Schwinger functions in this theory. Using this expression we obtain the quantum corrections to the effective background and the $β$-functions, which are known to vanish at the self-dual point. The case of degenerate noncommutativity is also considered. Our main result can be straightforwardly applied to any polynomial self-interaction of the scalar field and we consider that the worldline approach could be useful for studying effective actions of noncommutative gauge fields as well as in other non-local models or in higher-derivative field theories.
