摘要:

我们发展了无限自旋自由$4D, {\cal N}=1$超对称理论的一个完整的离壳拉格朗日描述。玻色子场和费米子场用带点指数和不带点指数的自旋张量场来表示。在BRST方法下,导出了玻色子和费米子无限自旋场进入壳层超对称模型的相应拉格朗日量。该超对称模型的拉格朗日量是用复无限自旋玻色子场和无限自旋费米子Weyl场的超对称变换来表示的。在壳层上的超对称拉格朗日量的场可以看作是六个无限自旋手征和反手征多重态的分量。这些多重态被扩展到相应的无限自旋手征和反手征超场,使两个手征和反手征超场的组件之间包含的基本领域的无限自旋超多重态和额外的四个手征和反手征超场只包含所需的拉格朗日公式的辅助领域。超场拉格朗日是根据这六个手征和反手征超场构造的,我们证明了这个超场拉格朗日的分量形式与消除了构造(反)手征超场时加入的分量场后的先前发现的分量超对称拉格朗日完全一致。

英文摘要:

We develop a complete off-shell Lagrangian description of the free $4D, {\cal N}=1$ supersymmetric theory of infinite spin. Bosonic and fermionic fields are formulated in terms of spin-tensor fields with dotted and undotted indices. The corresponding Lagrangians for bosonic and fermionic infinite spin fields entering into the on-shell supersymmetric model are derived within the BRST method. Lagrangian for this supersymmetric model is written in terms of the complex infinite spin bosonic field and infinite spin fermionic Weyl field subject to supersymmetry transformations. The fields involved into the on-shell supersymmetric Lagrangian can be considered as components of six infinite spin chiral and antichiral multiplets. These multiplets are extended to the corresponding infinite spin chiral and antichiral superfields so that two chiral and antichiral superfields contain among the components the basic fields of an infinite spin supermultiplet and extra four chiral and antichiral superfields containing only the auxiliary fields needed for the Lagrangian formulation. The superfield Lagrangian is constructed in terms of these six chiral and antichiral supefields, and we show that the component form of this superfield Lagrangian exactly coincides with the previously found component supersymmetric Lagrangian after eliminating the component fields added to construct (anti)chiral superfields.
