Towards the structure of a cubic interaction vertex for massless integer higher spin fields

Abstract

The structure of a cubic Lagrangian vertex is clarified for irreducible fields of helicities $s_1,s_2,s_3$ in a $d$-dimensional Minkowski space. An explicit form of the operator ${\mathcal{Z}}_j$ entering the vertex in a non-multiplicative way (examined in arXiv:2105.12030[hep-th] for $j=1$) is obtained. The solution is found within the BRST approach with complete BRST operators, which contain all constraints corresponding to the conditions that extract the irreducible fields, including trace operators.
