N = 1超对称自旋泡沫的粒子解释

The particle interpretation of N = 1 supersymmetric spin foams

V. Baccetti, E. R. Livine, J. P. Ryan

摘要:

我们表明,N = 1超对称BF理论在3D导致超对称自旋泡沫振幅通过晶格离散化。此外,通过分析超对称量子振幅,我们表明,它们可以重新解释为三维引力耦合到嵌入费米子费曼图。

英文摘要:

We show that N = 1 supersymmetric BF theory in 3d leads to a supersymmetric spin foam amplitude via a lattice discretisation. Furthermore, by analysing the supersymmetric quantum amplitudes, we show that they can be re-interpreted as 3d gravity coupled to embedded fermionic Feynman diagrams.
