平移不变性、对易关系与紫外/红外混合

Translation Invariance, Commutation Relations and Ultraviolet/Infrared Mixing

Salvatore Galluccio, Fedele Lizzi, Patrizia Vitale

摘要:

我们表明,紫外/红外混合的非对易场论与格罗内沃尔德-Moyal产品,其中一些(但不是全部)紫外发散成为红外,是一个通用的功能,conventional不变的关联产品。我们发现,与一个明确的计算,出现在非平面图的相位是一个由交换器的坐标,非对易时空的半经典泊松结构。我们这样做的显式计算所代表的通用产品。

英文摘要:

We show that the Ultraviolet/Infrared mixing of noncommutative field theories with the Gronewold-Moyal product, whereby some (but not all) ultraviolet divergences become infrared, is a generic feature of translationally invariant associative products. We find, with an explicit calculation that the phase appearing in the nonplanar diagrams is the one given by the commutator of the coordinates, the semiclassical Poisson structure of the non commutative spacetime. We do this with an explicit calculation for represented generic products.
