Studying neutrinos at the high energy frontier with FASER$\nu$ at the LHC

Not scheduled


Dr Akitaka Ariga (University of Bern)


FASER$\nu$ is a dedicated neutrino detector in the FASER experiment to study high-energy neutrinos from the LHC, which got approved by CERN in December 2019. A 1.2-tonnes emulsion-based detector will be located at 480 m downstream of the ATLAS interaction point. The unique experimental setup allows measuring three-flavor neutrino cross sections at the currently uncharted energy range between 350 GeV and 6 TeV. Furthermore, the channels associated with heavy quark (charm and beauty) production will be studied. FASER$\nu$ will take data in Run 3 of LHC operation (2021-2024), which would yield roughly 1300 $\nu_e$, 20000 $\nu_{\mu}$, and 20 $\nu_{\tau}$ interacting in the detector. The physics motivation, overview of the FASER$\nu$ project and the candidate neutrino events from the 30 kg neutrino detector in the 2018 pilot run (correcting 12.5 $fb^{-1}$ of data) will be reported.
