First Observation of Collider Neutrinos with FASER and Implications for Astroparticle Physics

Abstract: Hadron colliders, like the LHC, are our primary tool to explore and expand our understanding of nature at the energy frontier. In addition, they are also the source of the most energetic human-made neutrinos. Indeed, the LHC produces a unique beam of TeV-energy neutrinos of all three flavors along the direction of the proton beams. The FASER experiment was built to exploit this opportunity by studying the production and interactions of these neutrinos. The experiment recently reported the first direct observation of neutrinos at the LHC, and also performed a first search for dark photons. In this talk, I will present FASER and its first results, discuss connections and potential for astro-particle physics, introduce a proposal for the continuation of this forward physics program for the HL-LHC in form of a ‘Forward Physics Facility’, and aim to stimulate a fruitful discussion with my audience.
