Theoretical developments in the SMEFT at dimension-8 and beyond
Simone Alioli, Radja Boughezal, Weiguang Cao +24
In this contribution to the Snowmass 2021 process we review theoretical developments in the Standard Model Effective Field Theory (SMEFT) with a focus on effects at the dimension-8…
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…
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-…
Enumerating higher-dimensional operators with on-shell amplitudes
Gauthier Durieux, Camila S. Machado
We establish a simple formula for the minimal dimension of operators leading to any helicity amplitude. It eases the systematic enumeration of independent operators from the constr…
Gravitational wave probes of axion-like particles
Camila S. Machado, Wolfram Ratzinger, Pedro Schwaller +1
We have recently shown that axions and axion-like particles (ALPs) may emit an observable stochastic gravitational wave (GW) background when they begin to oscillate in the early un…
The Super-Planckian Axion Strikes Back
Nayara Fonseca, Benedict von Harling, Leonardo de Lima +1
We present a novel framework for obtaining large hierarchies in axion decay constants as well as trans-Planckian field excursions, with no need for tuning or a large number of fiel…
