All-Order Helicity Selection Rules in Effective Field Theories
Luigi C. Bresciani, Nudzeim Selimovic
Using on-shell methods, we derive an all-order non-renormalization theorem for general four-dimensional effective field theories, relying on Poincaré invariance and unitarity. Each…
Opening the Topological Portal to Dark Sectors with Colliders
Joe Davighi, Admir Greljo, Lia Schöneweiß +1
We study the phenomenology of the topological portal between QCD and pseudo-Nambu--Goldstone dark matter proposed in~\cite{Davighi:2024zip}. We construct a weakly coupled ultraviol…
Neutron Star Bounds on Muonic Fifth Forces from Picometer to Meter Scales
Damiano F. G. Fiorillo, Alessandro Lella, Georg G. Raffelt +2
Testing muonic fifth forces is difficult because muons are scarce in ordinary matter. However, they are abundant in neutron stars. We show that this population responds coherently…
Production of Leptophilic Bosons in Ultradegenerate Relativistic Matter
Damiano F. G. Fiorillo, Alessandro Lella, Georg G. Raffelt +2
Neutron stars (NSs) are powerful factories for new particles with masses up to the 100~keV range. These compact stars contain significant amounts of protons, electrons, and muons.…
