抄録

Neutrinos from a particle collider have never been directly detected. FASER? 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, we installed a pilot detector 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 observed the first candidate vertices, which were consistent with neutrino interactions. A 2.7s 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 ~2,000 ?e, ~6,000 ?µ, and ~40 ?t interactions in the detector. Herein, we present the status and plan of FASER? and report neutrino detection in the 2018 data.
