We develop an effective field theory of a generic massive particle of any spin and, as an example, apply this to study higher-spin dark matter (DM). Our formalism does not introduce unphysical degrees of freedom, thus avoiding the potential inconsistencies that may appear in other field-theoretical descriptions of higher spin. Being a useful reformulation of the Weinberg's original idea, the proposed effective field theory allows for consistent computations of physical observables for general…

On-shell effective theory for higher-spin dark matter
We apply the on-shell amplitude techniques in the domain of dark matter. Without evoking fields and Lagrangians, an effective theory for a massive spin-$S$ particle is defined in terms of on-shell
A complete effective field theory for dark matter
Abstract We present an effective field theory describing the relevant interactions of the Standard Model with an electrically neutral particle that can account for the dark matter in the Universe.
Confronting spin-3/2 and other new fermions with the muon g-2 measurement
The new measurement of the muon’s anomalous magnetic moment released by the Muon g-2 experiment at Fermilab sets strong constraints on the properties of many new particles. Using an effective field
Dark matter interacting via a massive spin-2 mediator in warped extra-dimensions
Abstract We study dark matter interacting via a massive spin-2 mediator. To have a consistent effective theory for the spin-2 particle, we work in a warped extra-dimensional model such that the
FIMP Dark Matter in Clockwork/Linear Dilaton extra-dimensions
We study the possibility that Dark Matter (DM) is made of Feebly Interacting Massive Particles (FIMP) interacting just gravitationally with the Standard Model particles in the framework of a
Gauging the Higher-Spin-Like Symmetries by the Moyal Product. II
Continuing the study of the Moyal Higher Spin Yang–Mills theory started in our previous paper we provide a detailed discussion of matter coupling and the corresponding tree-level amplitudes. We also
Higher-spin particles at high-energy colliders
Using an effective field theory approach for higher-spin fields, we derive the interactions of colour singlet and electrically neutral particles with a spin higher than unity, concentrating on the
Massive Higher-Spin Multiplets and Asymptotic Freedom in Quantum Gravity
We consider massive higher-spin multiplets that contain both standard and purely virtual degrees of freedom coupled to quantum gravity and compute their contributions to the gravitational beta
Weaving the covariant three-point vertices efficiently
An efficient algorithm is developed for compactly weaving all the Lorentz covariant three-point vertices in relation to the decay of a massive particle X of mass mX and spin J into two particles M1,2
