In this talk we will go on a trip to the world of neutrinos, the elusive particles that are constantly streaming through us unnoticed. We will also have a glimpse at the neutrino experiments and the Fermilab program(s) that are working towards shedding light upon the mysteries around the neutrinos.

MicroBooNE is a liquid argon time projection chamber that operates in the Booster Neutrino Beam at Fermilab. The detector provides high-resolution imaging of neutrino interactions with a low threshold and full angular coverage. Thanks to a high event rate and several years of continuous operation, the MicroBooNE collaboration has obtained the world's largest dataset of neutrino-argon scattering events. The MicroBooNE collaboration recently released a series of measurements aimed at investigating the nature of the excess of low-energy electromagnetic interactions observed by the MiniBooNE collaboration. In this talk, we will present the latest results from a series of three independent analyses leveraging different reconstruction paradigms which look for an anomalous excess of electron neutrino events in the Fermilab Booster Neutrino Beam. This talk will present these recent results from MicroBooNE and discuss the future physics goals of Fermilab’s flagship experiment, DUNE (Deep Underground Neutrino Experiment).

She completed her bachelors from St. Xaviers College, Kolkata and Masters from IIT Madras in Physics. As a PhD student at The University of Mississippi, She worked on the Muon g-2 experiment and was stationed at Fermilab since January 2018. My PhD dissertation is on “Search for CPT and Lorentz Invariance Violation in the Muon g-2 experiment at Fermilab”. She joined the MicroBooNE and DUNE experiments as a postdoctoral research associate within the Computational Science and AI (Artificial Intelligence) Directorate at Fermilab in 2021. Her diverse background in physics ranges from working on hardware upgrades, analyzing physics data in both muon and neutrino.
