SUMMARY:Search for an Excess of Electron Neutrino Interactions in Micr
 oBooNE Using Multiple Final State Topologies\, Physics Department Coll
 oquium\, Bryce Littlejohn\, IIT
DESCRIPTION:I will present a measurement of electron neutrino interact
 ions from the Fermilab Booster Neutrino Beam using the MicroBooNE liqu
 id argon time projection chamber performed to address the nature of th
 e excess of low energy interactions observed by the MiniBooNE collabor
 ation. Observation of an excess of electron neutrino detections in Mic
 roBooNE would represent clear evidence of new physics in the neutrino 
 sector\, such as the existence of new neutrino mass states beyond thos
 e associated with the three Standard Model neutrinos.  Three independe
 nt electron neutrino searches were performed by MicroBooNE across mult
 iple single electron final states\, including an exclusive search for 
 two-body scattering events with a single proton\, a semi-inclusive sea
 rch for pion-less events\, and a fully inclusive search for events con
 taining all hadronic final states. With differing signal topologies\, 
 statistics\, backgrounds\, reconstruction algorithms\, and analysis ap
 proaches\, the results are found to be consistent with the nominal ele
 ctron neutrino rate expectations from the Booster Neutrino Beam and no
  excess of electron neutrino events is observed.  I will summarize imp
 ortant details of MicroBooNE's new centerpiece result\, while also pro
 viding some broader context on its impact on searches for physics beyo
 nd the Standard Model in the neutrino sector.
