非对易Minkowski空间上的算子与矩阵基

Propagators and Matrix Basis on Noncommutative Minkowski Space

Andre Fischer, Richard J. Szabo

摘要:

我们描述了一个解析延续的欧几里得Grosse-Wulkenhaar和LSZ模型,定义了一个单参数家庭的对偶协变非交换场论插值之间的欧几里得和闵可夫斯基空间版本的这些模型,并提供了一个替代正规化通常的费曼处方。这种正则化允许一个矩阵模型表示的场论在一个复杂的一般基础的朗道波函数。计算了相应的传播子,并与场论的Feynman传播子进行了比较。被调节的量子场论被证明是UV/IR对偶协变的。我们研究了正则化传播子在位置和矩阵空间表示中的渐近性,并确认它们一般具有良好的衰减行为,如在欧几里得情况下。

英文摘要:

We describe an analytic continuation of the Euclidean Grosse-Wulkenhaar and LSZ models which defines a one-parameter family of duality covariant noncommutative field theories interpolating between Euclidean and Minkowski space versions of these models, and provides an alternative regularization to the usual Feynman prescription. This regularization allows for a matrix model representation of the field theories in terms of a complex generalization of the usual basis of Landau wavefunctions. The corresponding propagators are calculated and identified with the Feynman propagators of the field theories. The regulated quantum field theories are shown to be UV/IR-duality covariant. We study the asymptotics of the regularized propagators in position and matrix space representations, and confirm that they generically possess a comparably good decay behaviour as in the Euclidean case.
