非交换 R^d 上量子场论的重整化, I. 标量场

高能物理 - 理论 2009-10-31 v4

摘要

非交换费曼图是一种带状图,可以画在带边界的亏格 gg 二维曲面上。我们用拓扑术语表述了非交换费曼图的一般收敛定理,并在标量场论中的某些图类上予以证明。我们提出了 Bogoliubov-Parasiuk 递推减除公式的非交换类比,并证明了来自类 Ωd\Omega_d 的减除图满足收敛定理的条件。对于 \red\re^d 上的通用标量非交换量子场论,类 Ωd\Omega_d 小于该理论中全部图的类。这使得非交换场论的微扰可重整化问题悬而未决。我们评论了超对称如何改善这一状况,并建议非交换的 Wess-Zumino 模型类比是可重整化的。
