Study of TeV Neutrinos in the Faser Experiment at the LHC

The Large Hadron Collider (LHC) copiously produces high-energy neutrinos at TeV-energy scale, however, none of them has ever been detected. The FASER Collaboration is going to study the high energy neutrinos from the LHC with a flavor-sensitive detector, so-called FASER$\nu$. FASER$\nu$ would open a new domain of neutrino researches at the high energy frontier of man-made neutrinos and it has a potential to discover physics beyond the standard model. In Run 3 of LHC operation in 2021–2023, FASER$\nu$ is expecting about 20,000 $\nu_{\mu}$, 1300 $\nu_e$ and 20 $\nu_{\tau}$ interactions occurring in the detector. The FASER$\nu$ has been approved since December 2019 and the collaboration is preparing for the data taking in 2021.
