Higgs Couplings at a Future Wakefield Collider

Katherine Fraser, Simon Knapen, Kevin Langhoff +1

We explore the potential of multiple possible future 10 TeV wakefield colliders to measure electroweak couplings of the Higgs boson. We find that the beam-beam interactions are not…

Bounds on axion-like particles from fully merged photons at the LHC

Simon Knapen

I show that, in the mass range , the strongest current bound on axion-like particles (ALPs) coupled to photons comes from very high energy $a…

Dark Matter Detection Using Phonon Sensing in Amorphous Materials

Itay M. Bloch, Simon Knapen, Xinran Li +2

We present a concept for a tabletop-scale detector with an amorphous target designed to search for dark matter absorption into phonon excitations. In crystalline materials, absorpt…

Searches for electroweak states at future plasma wakefield colliders

So Chigusa, Simon Knapen, Toby Opferkuch +3

We quantify the discovery potential of future multi-TeV plasma wakefield colliders for new electroweak multiplets. We include beam-beam effects through realistic luminosity spectra…

Spin-Dependent Scattering of Sub-GeV Dark Matter: Models and Constraints

Stefania Gori, Simon Knapen, Tongyan Lin +2

We calculate the scattering rate of sub-GeV dark matter in solid-state targets for spin-dependent dark matter -- nucleon interactions. For dark matter particles with mass below 100…

CODEX-b: Opening New Windows to the Long-Lived Particle Frontier at the LHC

Giulio Aielli, Juliette Alimena, Saul Balcarcel-Salazar +50

This document is written as a contribution to the European Strategy of Particle Physics (ESPP) update. We offer a detailed overview of current developments and future directions fo…
