Massive gravity has seen a resurgence of interest due to recent progress which has
overcome its traditional problems, yielding an avenue for addressing important open …

We write down an action for a charged, massive spin two field in a fixed Einstein
background. Despite some technical problems, we argue that in an effective field theory …

Higher Spin Gravity refers to extensions of gravity including at least one field of spin greater
than two. These extensions are expected to provide manageable models of quantum gravity …

Massive spin s⩾ 3/2 fields can become partially massless in cosmological backgrounds. In
the plane spanned by m2 and Λ, there are lines where new gauge invariances permit …

Using the light-cone formulation of relativistic dynamics, we develop various methods for
constructing cubic interaction vertices and apply these methods to the study of higher spin …

The explicit covariant actions and propagators are given for fields describing particles of all
spins and masses, in any spacetime dimension. Massive particles are realized as …

We discuss string spectra in the low-tension limit using the BRST formalism, with emphasis
on the role of triplets of totally symmetric tensors and spinor-tensors and their …

We analyze the physics of massive spin-2 fields in (A) dS backgrounds and exhibit that: The
theory is stable only for masses m2⩾ 2Λ/3, where the conserved energy associated with the …

Using the light-cone gauge approach to relativistic field dynamics, we study arbitrary spin
fermionic and bosonic fields propagating in flat space of dimension greater than or equal to …

We construct the Lagrangian description of arbitrary integer higher-spin massless fields on
the background of the D-dimensional anti-de Sitter space. The operator constraints in …
