Neutrino Goals:(2) Fully exploit the short-baseline neutrino program
Objective:• Determine if there is a ~1eV sterile neutrino
Short-baseline oscillation program• MicroBooNE will investigate MiniBooNE
low energy excess• Adding SBND and ICARUS to complete the
3-detector suite will fully probe the sterile neutrino hypothesis
Cosmological constraints• SPT-3G will improve constraint on number
of neutrinos by 2x• Optical surveys (e.g. DESI, LSST) + CMB-S4
will also improve constraint on sum of neutrino masses.Stage 5 cosmic survey under discussion by the community.
• First “Topics in Cosmic Neutrino Physics Workshop” in Oct 2019. More activities in this direction as part of a future Cosmic Physics Center (CPC).
Will leverage information in terrestrial & cosmic probes to achieve our objective.
