DUNE, A Future Neutrino Experiment, and Its New Physics Potential

Abstract: With the discovery of the Higgs-like particle in 2012, which has been sought for over 5 decades and the subsequent measurements of its properties getting closer and closer to that predicted by the Standard Model, it is increasingly important for the field of high energy physics to fully understand the neutrino sector which deviates from the Standard Model. The precision measurements of oscillation properties, the mass hierarchy and the CP phase measurements demand high intensity neutrino beams and large mass detectors. These new facilities, however, provide opportunities to search for dark matter which could be produced in the beams and for boosted dark matter which originates from the galactic center. In this talk, I will discuss the searches for low mass dark matter at the Deep Underground Neutrino Experiment, the U.S.flagship neutrino experiment, the progress and timeline of the experiment, including the status of its prototype detectors, and of the potential for early physics at DUNE.
Bio: Dr. Jaehoon Yu, Professor of Physics at University of Texas - Arlington, is a high energy particle physicists who has been playing leadership roles in several large scale (600 - 3000 members) experiments. He obtained his Ph.D. in 1993 from Stony Brook University and subsequently did his postdoctoral trainings with the University of Rochester and Fermilab. He then became a tenure track associate scientist at Fermilab in 1998 and led the commissioning of the upgraded DZero detector as the first commissioning coordinator, setting the stage. After the completing the commissioning leadership successfully, he joined the University of Texas at Arlington in 2001 as a professor of physics. He has worked on precision measurement of the strong coupling constant using the charged weak boson produced with jets at DZero as his Ph.D. thesis topic.
Leveraging this experience, he contributed to searches for the Higgs particle at DZero through its discovery and precision coupling measurement at ATLAS which he joined in 2005. He has also worked on development of precision digital calorimeter for the International Linear Collider, playing a leadership role in coordinating test beam activities worldwide and serving in the ILC physics group. In 2013, he has joined the Long Baseline Neutrino Experiment and led the collaboration for detector R&D activities. LBNE is a previous incarnation of the Deep Underground Neutrino Experiment (DUNE), the $1B U.S. flagship experiment hosted by Fermi National Accelerator Laboratory near Chicago with four large detectors holding over 75,000 tons of liquid argon in an underground mine in South Dakota with the turn on in 2026. He has just completed in 2018 constructing a 6mx6mx6m field cage electrical for a large scale prototype detector at CERN and has created and been leading the Beyond the Standard Model physics at the next generation neutrino experiments.
