MicroBooNE is a liquid argon time projection chamber (LArTPC) neutrino detector. One of its primary goals is to measure neutrino interaction cross sections on argon within the detector. These measurements will inform model developments and simulations for future LArTPC experiments including SBN and DUNE. Current electron neutrino cross section measurements on argon are limited but are particularly important for DUNE. This poster presents progress towards an electron neutrino charged-current cross section measurement without visible pions in the final state using data collected in the Booster Neutrino Beam at Fermilab. Events with and without visible protons in the final state are measured separately, with single differential cross sections in several kinematic variables presented for events with visible protons, and a total cross section measurement for events without visible protons.
