三维N=4超共形超场论

Three-dimensional N=4 superconformal superfield theories

B. M. Zupnik

摘要:

D=3,N=4超对称中的镜像映射连接了左右SU(2)自同构群以及相应的N=4超多重态的超场表示。镜像N=4调和超空间使用两个SU(2)群的调和函数和两种格拉斯曼解析性。在这些调和超空间中定义了N=4的不可约左、右超多重态。我们分析了N=4超共形相互作用的规范和物质的超场和自发击穿的超共形对称性。最有趣的超共形作用量具有镜像对称性,包含阿贝尔左、右规范超场的两个非线性项,还包含N=4的BF相互作用,它产生了规范场的拓扑质量和标量场与赝标场的非平凡相互作用.左右N=4超多重态的最小相互作用可以包含在这个阿贝尔规范理论中。我们还考虑了非线性N=4规范超场相互作用。

英文摘要:

The mirror map in the D=3, N=4 supersymmetry connects the left and right SU(2) automorphism groups and also the superfield representations of the corresponding N=4 supermultiplets. The mirror N=4 harmonic superspaces use the harmonics of two SU(2) groups and two types of the Grassmann analyticity. The irreducible left and right N=4 supermultiplets are defined in these harmonic superspaces. We analyze the N=4 superconformal interactions of the gauge and matter superfields and the spontaneous breakdown of the superconformal symmetry. The most interesting superconformal action possesses the mirror symmetry and contains two nonlinear terms of the abelian left and right gauge superfields, and also the mixing N=4 BF interaction which yields the topological masses of the gauge fields and the nontrivial interaction of the scalar and pseudoscalar fields. The minimal interactions of the left and right N=4 hypermultiplets can be included to this abelian gauge theory. We consider also the nonlinear N=4 gauge superfield interactions.
