Stefano Soleti (Oxford/Harvard U.) "Searching for a Low-Energy Excess at MicroBOONE"
January 8, 2019 @ 4:00 pm - 5:00 pm
The last twenty years have seen a spectacular improvement in our understanding of neutrino oscillations and neutrino physics in general. However, several experiments have shown some puzzling results which do not fit the standard three-flavor mixing scheme of neutrinos. In particular, the LSND and MiniBooNE experiments observed an excess of low-energy electron neutrinos, which could be interpreted as the signature of a fourth, non-weakly interacting, neutrino. The goal of the MicroBooNE experiment, a liquid argon time projection chamber currently running at Fermilab, is to assess the nature of this excess. In this talk the first automated electron neutrino search in a LArTPC will be presented. This result is the first step towards a measurement of the low-energy excess at MicroBooNE.
