具有SU(2)函数的空间回路图

Loop diagrams in space with SU(2) fuzziness

H. Komaie-Moghaddam, M. Khorrami, A. H. Fatollahi

摘要:

本文在三维坐标非对易且满足SU(2)李代数的标量场理论中研究了圈修正的结构。特别地,$ϕ^4$标量理论中的2点和4点函数是以1-循环阶计算的。由于动量空间是紧致的,所以该理论是UV有限的。它示出的非平面校正是成比例的一维$δ$ -函数,而不是一个三维的,所以在过渡率只有平面校正作出贡献。

英文摘要:

The structure of loop corrections is examined in a scalar field theory on a three dimensional space whose spatial coordinates are noncommutative and satisfy SU(2) Lie algebra. In particular, the 2- and 4-point functions in $ϕ^4$ scalar theory are calculated at the 1-loop order. The theory is UV-finite as the momentum space is compact. It is shown that the non-planar corrections are proportional to a one dimensional $δ$-function, rather than a three dimensional one, so that in transition rates only the planar corrections contribute.
