The COSMIC WISPers White Paper: The physics case for Weakly Interacting Slim Particles
Ariel Arza, Deniz Aybas, Shyam Balaji +124
Axions and other very weakly interacting slim particles (WISPs), with masses below 1 GeV, arise naturally in many extensions of the Standard Model of particle physics. In particula…
Improving Neutrino Oscillation Measurements through Event Classification
Sebastian A. R. Ellis, Daniel C. Hackett, Shirley Weishi Li +2
Precise neutrino energy reconstruction is essential for next-generation long-baseline oscillation experiments, yet current methods remain limited by large uncertainties in neutrino…
Soft Gravitons, Hard Truths: Infrared Safety of Particle Processes in a Gravitational-Wave Background
Wen-Yuan Ai, Sebastian A. R. Ellis, Josef Pradler
Gravitational waves are thought to propagate unattenuated through matter due to a cancellation between graviton absorption and stimulated emission inferred from leading-order soft-…
A Prototype Hybrid Mode Cavity for Heterodyne Axion Detection
Zenghai Li, Kevin Zhou, Marco Oriunno +7
In the heterodyne approach to axion detection, axion dark matter induces transitions between two modes of a microwave cavity, resulting in a parametrically enhanced signal power. W…
Summary Report of the Physics Beyond Colliders Study at CERN
R. Alemany Fernández, M. Au, G. Arduini +80
The Physics Beyond Collider (PBC) Study Group was initially mandated by the CERN Management to prepare the previous European Particle Physics Strategy Update for CERN projects othe…
Classical (and Quantum) Heuristics for Gravitational Wave Detection
Raffaele Tito D'Agnolo, Sebastian A. R. Ellis
We derive a lower bound on the sensitivity of generic mechanical and electromagnetic gravitational wave detectors. We consider both classical and quantum detection schemes, althoug…
