Abstract:

The MicroBooNE experiment was designed primarily to explore the nature of the previously observed low-energy excess in electron neutrino candidates in the MiniBooNE experiment located in the Booster Neutrino Beamline at Fermi National Accelerator Laboratory. Using an 85-ton active volume Liquid Argon Time Projection Chamber (LArTPC) with its excellent electron versus photon separation capability, the MicroBooNE experiment searches for an anomalous excess with an electromagnetic signature in several neutrino-induced interaction channels. In this talk, I will report the latest search results based on data taken from February 2016 to July 2018 in several exclusive and inclusive charged-current electron neutrino-induced interaction channels as well as a neutral-current Δ radiative decay channel.

 

Biography:

Dr. Xin Qian got his Ph.D from Duke University in 2010 on experimental nuclear physics research work understanding the nucleon spin structure with an electron beam. He subsequently became the Robert A. Milikan postdoctoral scholar at California Institute of Technology working on the Daya Bay reactor neutrino experiment. He joined Brookhaven National Lab as an assistant physicist in 2013, and was promoted through the ranks to tenured physicist in 2020. He won 2014 early career award from U.S. Department of Energy to develop Liquid Argon Time Projection Chamber technology for precision neutrino physics, 2016 Breakthrough prize of fundamental physics as a member of Daya Bay collaboration, and 2017 European Physics Society Young Experimental Scientist Prize.
