    Physics Colloquium

    "Changing Flavor: the Universe's Weirdest Particle"

    Presented by Kirsty Duffy - Leona Woods Award Winner, FNAL

    3:30 pm, Large Seminar Room, Bldg. 510

    Tuesday, November 5, 2019, 3:30 pm

    Neutrinos are some of the most abundant–but elusive–constituents of matter in the universe. It has been firmly established that neutrinos can change flavor (or "oscillate"), as recognized by the 2015 Nobel Prize, and in recent years the field has moved beyond the "discovery" phase to focus on precise measurements of the parameters that determine neutrino oscillation. As our understanding improves, it opens doors to new discoveries about the nature of this little-understood particle. This is a very exciting time in neutrino physics there exists a wealth of fascinating questions to investigate, including recent tantalizing hints of large neutrino-sector CP violation, and we are rapidly developing the tools to answer them. As the United States HEP community leads the next generation of neutrino oscillation experiments, I will give an overview of the field: from the initial discovery of the neutrino, to the first evidence for oscillation, to the most recent results from current long-baseline oscillation experiments such as T2K and NOvA. I will finish by discussing the exciting future prospect of the Deep Underground Neutrino Experiment and the liquid argon time projection chamber technology that makes it possible, including recent results and examples from my own work on MicroBooNE, a liquid argon neutrino detector currently taking data at Fermilab

    Presented by Dr. Massimiliano Delferro, Argonne National Laboratory

    Hosted by: Sanjaya Senanayake

    Systematic study of the interactions between organometallic catalysts and metal oxide support materials is essential for the realization of rational design in heterogeneous catalysis. In this talk, I will describe the stoichiometric and catalytic chemistry of a series of organometallic complex chemisorbed on a variety of metal oxides as a multifaceted probe for stereoelectronic communication between the support and organometallic center. Electrophilic bond activation was explored in the context of stoichiometric hydrogenolysis as well as catalytic hydrogenation, dehydrogenation, and H/D exchange. Strongly acidic modified metal oxides such as sulfated zirconia engender high levels of activity toward electrophilic bond activation of both sp2 and sp3 C–H bonds, including the rapid activation of methane at room temperature; however, the global trend for the supports studied here does not suggest a direct correlation between activity and surface Brønsted acidity, and more complex metal surface interactions are at play.

    Particle Physics Seminar

    "Latest neutrino cross-section results from MicroBooNE"

    Presented by Dr. Kirsty Duffy, FNAL

    Hosted by: Xin Qian

    MicroBooNE, the Micro Booster Neutrino Experiment at Fermilab, is an 85-ton active mass liquid argon time projection chamber (LArTPC) located in the Booster Neutrino Beam at Fermilab. The LArTPC technology with 3mm wire spacing enables high-precision imaging of neutrino interactions, which leads to high-efficiency, low-threshold measurements with full angular coverage. As the largest liquid argon detector worldwide taking neutrino beam data, MicroBooNE provides a unique opportunity to investigate neutrino interactions in neutrino-argon scattering at O(1 GeV) energies. These measurements are of broad interest to neutrino physicists because of their application to Fermilab Short Baseline Neutrino program and the Deep Underground Neutrino Experiment (which will both rely on LArTPC technology), as well as the possibility for new insights into A-dependent effects in neutrino scattering on heavier targets such as argon. In this seminar I will present the most recent cross-section results from MicroBooNE, including measurements of inclusive charged-current neutrino scattering, neutral pion production, and low-energy protons. Many of the results I will show represent the first measurements of these interactions on argon nuclei, as well as an exciting demonstration of the potential of LArTPC detector technology to improve our current understanding of neutrino scattering physics.

    "After the discovery of the Higgs Boson, the predictions of the Standard Model of particle physics can be extrapolated without inconsistencies all the way up to the Planck mass. Despite this tremendous success, we still remain in the dark about many open puzzles. Why is the weak interaction much stronger than gravity? What is the nature of Dark Matter? Are the strong, weak and electromagnetic forces a lower-energy manifestation of one single fundamental interaction? A possible solution to these questions is provided by Supersymmetry. The key assumption behind many natural supersymmetric models is that the masses of the gluinos, the top squarks and the higgsinos are near the TeV scale, thus within the LHC reach. In this presentation, I will introduce some of the theoretical and phenomenological arguments that motivate the quest for Supersymmetry. I will then outline how I searched for the above-mentioned particles using LHC Run-2 data collected by the ATLAS experiment. Finally, I will focus on my vision of the future and my research plans in high-energy experimental physics."
