摘要:

本文发展了背景场方法,用于研究N=3,d=3的Chern-Simons理论和N=3的调和超空间中的物质理论的经典和量子性质。作为直接的结果之一,我们证明了一个非重整化定理暗示相应的超图微扰理论的紫外有限性。我们还导出了在Chern-Simons背景下的一般超多重态和规范超场传播子。评估了具有两条和四条外线的领先超图。与非超对称理论相反,对大质量带电超多重态的量子修正主要是超杨-米尔斯作用量而不是陈-西蒙斯作用量。在N=3,d=3的Poincare超代数中,超多重态质量是由中心荷的一个常数三重态引起的。

英文摘要:

We develop the background field method for studying classical and quantum aspects of N=3, d=3 Chern-Simons and matter theories in N=3 harmonic superspace. As one of the immediate consequences, we prove a nonrenormalization theorem implying the ultra-violet finiteness of the corresponding supergraph perturbation theory. We also derive the general hypermultiplet and gauge superfield propagators in a Chern-Simons background. The leading supergraphs with two and four external lines are evaluated. In contrast to the non-supersymmetric theory, the leading quantum correction to the massive charged hypermultiplet proves to be the super Yang-Mills action rather than the Chern-Simons one. The hypermultiplet mass is induced by a constant triplet of central charges in the N=3, d=3 Poincare superalgebra.
