On-shell effective theory for higher-spin dark matter
Adam Falkowski, Giulia Isabella, Camila S. Machado
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- particle is defined in t…
Constructing massive on-shell contact terms
Gauthier Durieux, Teppei Kitahara, Camila S. Machado +2
The purely on-shell approach to effective field theories requires the construction of independent contact terms. Employing the little-group-covariant massive-spinor formalism, we p…
The silence of binary Kerr
Rafael Aoude, Ming-Zhi Chung, Yu-tin Huang +2
A non-trivial -matrix generally implies a production of entanglement: starting with an incoming pure state the scattering generally returns an outgoing state with non-…
Soft Matters, or the Recursions with Massive Spinors
Adam Falkowski, Camila S. Machado
We discuss recursion relations for scattering amplitudes with massive particles of any spin. They are derived via a two-parameter shift of momenta, combining a BCFW-type spinor shi…
