| contents | We revisit the literature on locality on de Sitter with the goal to organize the main results with respect to the representation theory of the isometry group of four dimensional de Sitter. We make use of the late-time behavior of two-point functions of principal and discrete series representation, both in physical and in field space and compare the role of the zero modes. Our overall conclusion is that when it comes to locality on de Sitter, analyzed in terms of cluster decomposition, the principal series representation that capture matter fields and discrete series representations that capture gauge fields show different behavior. Focusing on scalars as a first analysis, matter fields show explicit signs of respecting cluster decomposition while gauge fields do not. |
