IR Dynamics from UV Divergences: UV/IR Mixing, NCFT, and the Hierarchy Problem
Nathaniel Craig, Seth Koren
The persistence of the hierarchy problem points to a violation of effective field theory expectations. A compelling possibility is that this results from a physical breakdown of EF…
Freeze-Twin Dark Matter
Seth Koren, Robert McGehee
The mirror twin Higgs (MTH) addresses the little hierarchy problem by relating every Standard Model (SM) particle to a twin copy, but is in tension with cosmological bounds on ligh…
Exploring strong-field deviations from general relativity via gravitational waves
Steven B. Giddings, Seth Koren, Gabriel Treviño
Two new observational windows have been opened to strong gravitational physics: gravitational waves, and very long baseline interferometry. This suggests observational searches for…
The Weak Scale from Weak Gravity
Nathaniel Craig, Isabel Garcia Garcia, Seth Koren
We explore the prospects for bounding the weak scale using the weak gravity conjecture (WGC), addressing the hierarchy problem by violating the expectations of effective field theo…
Constructing Coulomb Branch Superamplitudes
Aidan Herderschee, Seth Koren, Timothy Trott
We study scattering amplitudes of massive BPS states on the Coulomb branch of super-Yang-Mills, utilising a little group covariant on-shell superspace for mass…
Massive On-Shell Supersymmetric Scattering Amplitudes
Aidan Herderschee, Seth Koren, Timothy Trott
We introduce a manifestly little group covariant on-shell superspace for massive particles in four dimensions using the massive spinor helicity formalism. This enables us to constr…
