Physics Briefing Book: Input for the 2026 update of the European Strategy for Particle Physics
Jorge de Blas, Monica Dunford, Emanuele Bagnaschi +127
The European Strategy for Particle Physics (ESPP) reflects the vision and presents concrete plans of the European particle physics community for advancing human knowledge in fundam…
The Price of a Large Electron Yukawa Modification
Lukas Allwicher, Matthew McCullough, Sophie Renner +2
The theoretical implications of an electron Yukawa modification are considered in the context of a possible Higgs pole run at FCC-ee, aimed at bounding this coupling. We start from…
New Physics at Tera-: Precision Renormalised
Lukas Allwicher, Matthew McCullough, Sophie Renner
We study the power of a Tera- run at FCC-ee for indirectly detecting or constraining heavy new physics. Our main finding is that nearly every new particle which matches at tree…
Doubling down on down-type diquarks
Christoph Englert, Christiane Mayer, Wrishik Naskar +1
Effective field theory-based searches for new physics at colliders are relatively insensitive to interactions involving only right-handed down-type quarks. These interactions can h…
