Neutrino Physics with Liquid Argon Detector

by Dr Stefan Soldner-Rembold

The seminar will give an overview of the liquid-argon neutrino physics programme at Fermilab. The Long Baseline Neutrino Facility (LBNF) will consist of a 1.2-megawatt proton beam neutrino source at Fermilab in Illinois, sending high-energy neutrinos to large liquid argon detectors located 1300 kilometers away and a mile underground at the Sanford Underground Research Facility. The detectors will be constructed and operated by the DUNE collaboration. The principle goals of this experiment are a comprehensive investigation of neutrino oscillations to test CP violation in the lepton sector, determining the ordering of the neutrino masses, and testing the three-neutrino paradigm. The experiment will perform a broad set of neutrino scattering measurements with the near detector and exploit the large, high-resolution, underground far detector for non-accelerator physics topics including atmospheric neutrino measurements, searches for nucleon decay, and measurement of astrophysical neutrinos especially those from a core-collapse supernova. The future long-baseline programme is complemented by a set of liquid-argon detectors (MicroBooNE, SBND, ICARUS) at short baseline that will search for sterile neutrinos and study neutrino interactions on liquid argon.
