DESCRIPTION:Speakers: Umut Kose (CERN EP-NU)\nFASER$\\nu$ at the LHC is de
 signed to directly detect collider neutrinos for the first time and study 
 their cross sections at high energies\, where no such measurements current
 ly exist. The detector will be located in the far-forward region of ATLAS.
  Deployment on the beam collision axis maximizes the flux of all three neu
 trino flavors\, and allows FASER$\\nu$ to measure their interaction cross-
 sections in the currently unexplored TeV energy range. For electron and ta
 u neutrinos\, these measurements will extend existing cross section measur
 ements to significantly higher energies. In 2018 we performed a pilot run 
 with the aims of measuring particle fluxes at the proposed detector locati
 on and of possibly detecting neutrino interactions for the first time at t
 he LHC. We installed a 30-kg lead/tungsten emulsion detector and collected
  data of 12.2 fb$^{-1}$. The analysis of this data has yielded several neu
 trino interaction candidates\, excluding the no-signal hypothesis at the 2
 $\\sigma$ level. During Run-3 of the LHC starting from 2022\, we will depl
 oy an emulsion detector with a target mass of 1.1 tons\, coupled with the 
 FASER magnetic spectrometer. This would yield roughly 2\,000 $\\nu_e$\, 8\
 ,000 $\\nu_{\\mu}$\, and 50 $\\nu_{\\tau}$ interacting in the detector. We
  present the status and prospects of FASER$\\nu$\, as well as the neutrino
  detection in the pilot run data.\n\nhttps://indico.ific.uv.es/event/6178/
