Title: "Examining Matter-Antimatter Asymmetry with DUNE"

Friday, April 29, 2022

Wilder 104 and Zoom
Intended Audience(s): Public

Abstract: Following the Big Bang, the universe was created in equal parts matter and antimatter. Yet, we live in a
matter dominated universe today. Leptonic charge conjugation × parity (CP) violation provides a possible
rationale to explain the matter-antimatter asymmetry we observe. Accelerator-based long-baseline
neutrino oscillation experiments are uniquely well-suited to examine CP violation in the lepton sector.
The Deep Underground Neutrino Experiment (DUNE) is a next generation long-baseline neutrino
oscillation program designed to determine the value of δCP within the context of standard three-flavor
mixing described by the Pontecorvo-Maki-Nakagawa-Sakata (PMNS) neutrino mixing matrix. A
performant near detector is required to realize DUNE neutrino oscillation sensitivities. I will introduce the
DUNE Near Detector, focusing on the atypical design necessitated by the unprecedented neutrino beam
intensity. I will discuss critical experimental challenges and highlight novel instrumentation, namely lowpower
custom ASICs with mixed-signal large-format PCB anodes for unambiguous 3D charge readout.
Recent results from the analysis of cosmic rays in a ton-scale prototype detector will be discussed.
