摘要:

利用高自旋场论的BRST方法,我们发展了一种构造四维、六维和十维平坦背景上N=1个超对称无质量高自旋场的立方相互作用顶点的通用技术。这种方法允许制定的方程的立方顶点,包括玻色子和费米子的高自旋场,并找到顶点的问题是减少到寻找这些方程的一致的解决方案。作为这一过程的一个实现,我们给出了场服从某些离壳约束的顶点的特解。结果表明,超对称性对顶点施加了额外的约束,并挑出一个特定的子类的解决方案。作为一般方案的一个具体应用,我们考虑了四维、六维和十维的超对称类杨-米尔斯系统,其中高自旋场在某些内部对称群下变换,以及相同维的类超引力系统。

英文摘要:

Using the BRST approach to higher spin field theories we develop a generic technique for constructing the cubic interaction vertices for N=1 supersymmetric massless higher spin fields on four, six and ten dimensional flat backgrounds. Such an approach allows formulation of the equations for cubic vertices including bosonic and fermionic higher spin fields, and the problem of finding the vertices is reduced to finding the consistent solutions to these equations. As a realization of this procedure, we present the particular solutions for the vertices where the fields obey some off-shell constraints. It is shown that the supersymmetry imposes additional constraints on the vertices and singles out a particular subclass of the solutions. As a concrete application of the generic scheme, we consider supersymmetric Yang-Mills-like systems in four, six and ten dimensions where the higher spin fields transform under some internal symmetry group, as well as supergravity-like systems in the same dimensions.
