NPA Seminar: Jamie Karthein, MIT, “Fluctuations of Conserved Charges for QCD Phase Diagram Characterization”

Fluctuations provide a powerful tool for elucidating the nature of strongly-interacting matter in the QCD phase diagram. In heavy-ion-collision systems, the net-particle number fluctuations are captured at the moment of chemical freeze-out. Studies of the chemical freeze-out via susceptibilities from Lattice QCD and the Hadron Resonance Gas model contribute to the characterization of the transition region of the QCD phase diagram.

Dissertation Defense: Ako Jamil, Yale University, “Rare Event Searches in Liquid Xenon with EXO-200 and nEXO”

Noble liquid time projection chambers are ubiquitously used to search for rare events such
as neutrinoless double beta decay or dark matter interactions. A detailed understanding of
light and charge transport in liquid xenon is of the utmost importance when modeling the
performance of these experiments.
In this talk I will present the design and physics reach of the proposed nEXO experiment,

YSEA Spring Into Books 2022 with Author Alvin Saperstein ’56 PhD, ‘Physics: Energy in the Environment’

Join us for a Yale Science and Engineering Association virtual conversation with Dr. Alvin M. Saperstein ’56 PhD, professor of physics emeritus and executive board member of the Center for Peace and Conflict Studies at Wayne State University as well as the former editor of the Physics and Society, a quarterly journal of the Forum on Physics and Society of the American Physical Society. He has been a Foster Fellow at the U.S.

NPA Seminar, Julieta Gruszko, UNC, “Discovering Neutrinoless Double-Beta Decay with LEGEND”

Why is the universe dominated by matter, and not antimatter? Neutrinos, with their changing flavors and tiny masses, could provide an answer. If the neutrino is a Majorana particle, meaning that it is its own antiparticle, it would reveal the origin of the neutrino’s mass, demonstrate that lepton number is not a conserved symmetry of nature, and provide a path to leptogenesis in the early universe. To discover whether this is the case, we must search for neutrinoless double-beta decay, a theorized process that would occur in some nuclei.

Life’s Edge: The Search for What it Means to be Alive

In Life’s Edge, Carl Zimmer explores the nature of life and investigates why scientists have struggled to draw its boundaries. He handles pythons, goes spelunking to visit hibernating bats, and even tries his hand at evolution. Zimmer visits scientists making miniature human brains to ask when life begins, and follows a voyage that delivered microscopic animals to the moon, where they now exist in a state between life and death. From the coronavirus to consciousness, Zimmer demonstrates that biology, for all its advances, has yet to achieve its greatest triumph: a full theory of life.

Causality at the Intersection of Simulation, Inference, Science, and Learning: Post-talk Conversation

The sciences are replete with high-fidelity simulators: computational manifestations of causal, mechanistic models. Ironically, while these simulators provide our highest-fidelity physical models, they are not well suited for inferring properties of the model from data. Professor Kyle Cranmer of New York University will describe the emerging area of simulation-based inference and describe how machine learning is being brought to bear on these challenging problems.

NPA Seminar, Simon Foreman, Perimeter Institute, "Detection of Cosmological 21cm Emission with CHIME"

Abstract: Intensity mapping of redshifted 21cm emission from neutral hydrogen holds great promise for learning about cosmology, as it provides an efficient way to map large volumes of the universe without the need to characterize individual luminous sources. The Canadian Hydrogen Intensity Mapping Experiment (CHIME) is a cylinder telescope located in Western Canada that was custom-built for this purpose, and that has collected several hundred days’ worth of data since it reached full observational capacity in late 2018.

WIDG Seminar, London Cooper-Troendle, Yale, “Extraction of an Inclusive Muon Neutrino Charged Current Differential Cross Section at MicroBooNE”

The MicroBooNE detector is a Liquid Argon Time Projection Chamber (LArTPC) located along the Booster Neutrino Beam (BNB) at Fermilab. One of its key physics goals is the measurement of neutrino-Argon interaction cross sections. Due to the detector’s fully active volume as well as its capability to offer a high-efficiency neutrino event selection, MicroBooNE is well suited produce the first ever triple-differential neutrino-Argon cross section.
