Abstract: Abstract We construct the effective field theory for a single massive higher-spin particle in flat spacetime. Positivity bounds of the S-matrix force the cutoff of the theory to be well below the naive strong-coupling scale,… read more here.

Abstract: In this work we discuss the cubic interactions for massless spin 3/2 gravitino with massive higher spin supermultiplets using three superblocks (2, 3/2), (5/2, 2) and (3, 5/2) as the first non-trivial examples. We use… read more here.

Abstract: Abstract In this paper we construct an unfolded formulation for the massive higher spin N = 1 supermultiplets in four dimensional AdS space. We use the same frame-like gauge invariant multispinor formalism that was used… read more here.

DOI: 10.1103/physrevlett.129.241601
Abstract: We propose a new, chiral description for massive higher-spin particles in four spacetime dimensions, which facilitates the introduction of consistent interactions. As proof of concept, we formulate three theories, in which higher-spin matter is coupled… read more here.
