Abstract

In this paper we construct the cubic interaction vertices for the four-dimensional massless higher spin bosonic fields with two-component multispinor indices. Such fields automatically satisfy the traceless conditions what simplify the equations determining the irreducible massless representation of the Poincaré group. Using the BRST approach we derive the equation for the cubic vertex and find the solutions for arbitrary spins \({{s}_{1}},{{s}_{2}},{{s}_{3}}\) and one special cases of maximal number of derivatives in the vertex.

论 d4 不可约无质量高自旋场及其立方相互作用

摘要

在本文中,我们构建了具有二分量多旋量指数的四维无质量高自旋玻色子场的立方相互作用顶点。这些场自动满足无痕条件,从而简化了确定庞加莱群的不可约无质量表示的方程。使用 BRST 方法,我们导出立方顶点的方程并找到任意自旋的解\({{s}_{1}},{{s}_{2}},{{s}_{3}} \)以及顶点中导数最大数量的一种特殊情况。
