Abstract
Neutrinos from a particle collider have never been directly detected. FASER$\nu$ at the Large Hadron Collider (LHC) is designed to detect such neutrinos for the first time and study their cross sections at TeV energies---at present, no such measurements are available at such high energies. In 2018, during LHC Run 2, a pilot detector was installed 480-m downstream of the ATLAS interaction point. In this pilot run, proton--proton collision data of 12.2 fb$^{-1}$ at a center-of-mass energy of 13 TeV were collected. We observe the first candidate vertices, which were consistent with neutrino interactions. A 2.7$\sigma$ excess of neutrino-like signal above the background was measured. This milestone opens a new avenue for studying neutrinos at the existing and future high-energy colliders. During LHC Run 3, which will commence in 2022, we will deploy an emulsion detector with a target mass of 1.1 tons, coupled with the FASER magnetic spectrometer. This will yield $\sim$2,000 $\nu_e$, 7,000 $\nu_{\mu}$, and 50 $\nu_{\tau}$ interactions in the detector. Herein, we present the status and plan of FASER$\nu$ and report neutrino detection in the 2018 data.
