Spin projection operators in (A)dS and partial masslessness

High Energy Physics - Theory 2020-01-08 v2

Abstract

We elaborate on the traceless and transverse spin projectors in four-dimensional de Sitter and anti-de Sitter spaces. The poles of these projectors are shown to correspond to partially massless fields. We also obtain a factorisation of the conformal operators associated with gauge fields of arbitrary Lorentz type (m/2,n/2)(m/2,n/2 ), with mm and nn positive integers.
