D=4,N=4超杨-米尔斯理论的离壳超空间重构

An off-shell superspace reformulation of D=4, N=4 super-Yang-Mills theory

Martin Cederwall

摘要:

D=4,N=4的超杨-米尔斯理论有一个用纯旋量超场表示的离壳超空间形式,它直接继承自D=10理论。这种超空间,特别是纯旋量变量的选择,不太适合处理固有的四维场,例如基于标量的超场,这是规范协变的,标量幂的迹是规范不变的。利用固有的四维纯旋量,在N=4超空间中给出了D=4,N=4超杨-米尔斯理论的一个重新表述.所有局部自由度都存在于基于物理标量的超场中。该方法适用于标量超场迹的标量算符的计算。

英文摘要:

D=4, N=4 super-Yang-Mills theory has an off-shell superspace formulation in terms of pure spinor superfields, which is directly inherited from the D=10 theory. That superspace, in particular the choice of pure spinor variables, is less suitable for dealing with fields that are inherently 4-dimensional, such as the superfields based on the scalars, which are gauge-covariant, and traces of powers of scalars, which are gauge-invariant. We give a reformulation of D=4, N=4 super-Yang-Mills theory in N=4 superspace, using inherently 4-dimensional pure spinors. All local degrees of freedom reside in a superfield based on the physical scalars. The formalism should be suited for calculations of correlators of traces of scalar superfields.
