First Results from MicroBooNE’s Low Energy Excess Search

<!--HTML--><p><span style="color:#000000">MicroBooNE is a neutrino experiment that utilizes a liquid argon time projection chamber (LArTPC) located on-axis in the Booster Neutrino Beam (BNB) at Fermilab. One of the experiment’s main goals is to search for excess low-energy electromagnetic-like events as seen by the MiniBooNE experiment, located just downstream of MicroBooNE in the BNB. This talk will present results from MicroBooNE’s first electron-like and photon-like searches. In the photon channel we perform a search for neutrino-induced neutral current resonant ∆(1232) baryon production followed by ∆ radiative decay, a Standard Model background process with a single photon in the final state. In the electron channel, three independent analyses targeting charged current electron neutrino interactions with different final-state topologies are performed. The talk will describe the detector and analysis tools developed to carry out these measurements, and present the analyses’ observations.</span></p> <p><strong><em>The seminar&nbsp;will take place in "hybrid format" with the speaker present in-person&nbsp;in the Main Auditorium (500/1-001).
