FASER
Appearance
FASER (ForwArd Search ExpeRiment) is one of the nine particle physics experiments in 2022 at the Large Hadron Collider at CERN. It is designed to both search for new elementary particles, as well as to detect and study the interactions of high-energy collider neutrinos. In March 2023, FASER reported the first observation of collider neutrinos, which was confirmed shortly after also by SND@LHC.
