Complementing the program of larger LHC experiments such as ATLAS and CMS, FASER explores the new physics landscape by seeking to detect feebly interacting particles (FIPs). It also aims to scrutinize the production mechanisms and interactions of high-energy (TeV- scale) neutrinos utilizing the specialized FASERν detector during Run-3 in a kinematic region uncovered by other experiments.
In this project, starting in June 2025, the team lead by Sfyrla and Rojo will exploit the unprecedented scientific potential of the FASER experiment for searches for new particles in final states involving both charged particles and photons, expanding on neutrino measurements with the electronic FASER detector, develop new Monte Carlo event generators tailored to the physics of TeV neutrinos, and constraining proton structure, forward hadron production, and small-x QCD phenomena by combining the resultant Run-3 neutrino measurements within a global theory analysis.
