Fermilab’s Search for Sterile Neutrinos with LAr1 and MicroBooNE

Fermilab will investigate sterile neutrinos through LAr1 (with MicroBooNE as a near detector) and MINOS+. The study is expected to take 4-6 years with a 680-ton fiducial volume. Statistical errors only. LAr1 serves as an engineering prototype for LArTPCs for Long Baseline physics. Collaborators Bonnie Fleming and Jenny Thomas are leading the MINOS+ project, which performs well at low Dm2. Together, MicroBooNE + LAr1 and MINOS+ cover LSND and MiniBooNE anti-neutrino regions effectively. Bonnie Fleming and Jenny Thomas have spearheaded this research.

  1. Fermilab will look for sterile neutrinos through LAr1 (with MicroBooNE as a near detector) and MINOS+ MicroBooNE + LAr1 19E20 PoT = 4-6 years for 680ton fiducial volume (~1-2kton total) Statistical Errors only – covers the entire region particularly well at high Dm2 LAr1 also serves as an engineering prototype for LArTPCs for Long Baseline physics (ie: LBNE, Soudan LBNE, GLADE) Bonnie Fleming Jenny Thomas

  2. MINOS+ MINOS+ plus Bugey which does very well at low Dm2 90% Confidence level Bonnie Fleming Jenny Thomas

  3. Purple line is MicroBooNE + LAr1 at 5 sigma (stat only) MINOS+ + Bugey is the Green line at 90% Confidence level Together they cover the LSND allowed region and the MiniBooNE anti-neutrino region with MicroBooNE +LAr1 best at high Dm2 and MINOS+ best at low Dm2 Bonnie Fleming Jenny Thomas
