NPA Seminar, Laura Havener, Yale, “Exploring QCD with quarks, gluons, and the quark-gluon plasma”

The smallest building blocks of matter, quarks and gluons (partons), are usually confined inside protons and neutrons (hadrons). At very high energies and temperatures, the partons become deconfined or “free”, forming a novel state of matter called the Quark-Gluon plasma (QGP). The QGP is produced at high-energy colliders by smashing together heavy ions and is found to be a nearly perfect fluid, but precise knowledge of its intrinsic properties is required. Jets are ideal probes of the QGP.

Inference Project Virtual Talk: Inference in a Nonconceptual World

Classical models of inference, such as those based on logic, take inference to be *conceptual* – i.e., to involve representations formed of terms, predicates, relation symbols, and the like. Conceptual representation of this sort is assumed to reflect the structure of the world: objects of various types, exemplifying properties, standing in relations, grouped together in sets, etc. These paired roughly algebraic assumptions (one epistemic, the other ontological) form the basis of classical logic and traditional AI (GOFAI).

Dissertation Defense: Kaicheng Li, Yale University, "Searching for the Electron Neutrino Anomaly with the MicroBooNE Experiment Using Wire-Cell Reconstruction"

The Micro Booster Neutrino Experiment (MicroBooNE) is a leading large-scale Liquid Argon Time Projection Chamber (LArTPC) experiment, designed for precision neutrino physics. The main scientific objectives of MicroBooNE include the investigation of the Low Energy Excess (LEE) observed by the MiniBooNE Experiment between 2002-2019 in the Booster Neutrino Beam (BNB) at Fermilab, the measurements of neutrino-argon interactions, and the research and development of LArTPC technology. This thesis focuses on understanding the MiniBooNE LEE through charged-current electron neutrino interactions.

WIDG Seminar: Will Tyndall, Yale, “Nearfield to Farfield Methods for Drone Beam Mapping”

Extracting cosmological 21 cm emission from the radio foregrounds which dominate requires precision calibration, including sub-percent measurements of the complex instrument beam. 21 cm cosmology experiments are typically driven to be compact transit interferometers with poor point-source sensitivity, and have found it difficult to constrain the beam shape to this precision with sky data alone. A technique that has been developed and demonstrated by multiple groups to address this is to transmit a calibrated RF signal from a drone into the telescope to measure the beam pattern.

WIDG Seminar: Evan Craft, Yale, “Beautiful and Charming Energy Correlators”

Understanding the detailed structure of energy flow within jets, a field known as jet substructure, plays a central role in searches for new physics, and precision studies of QCD. In this talk, I will discuss how reformulating jet susbtructure in terms of correlations of energy flow can be used to provide new insights into hadronization and intrinsic mass effects before confinement. In particular, I will show how energy correlators manifest the long-sought-after “dead-cone” effect of fundamental QCD.

Inference Project Virtual Talk and Conversation, Inference: A Logical-Philosophical Perspective

In this talk, Professor Paseau will describe some of his work on inference within mathematics and more generally. Inferences can be usefully divided into deductive or non-deductive. Formal logic studies deductive inference, the obvious question here being: which formal logic correctly captures it? His view, defended in his recent monograph One True Logic (Oxford UP, co-authored with Owen Griffiths), is that any such logic must be highly infinite. In this Inference Project event, he shall explain what this means and sketch some arguments for it.

Film Screening of Unconformity and Moderated Conversation with Writer and Director Jonathan DiMaio '09

An ambitious, rock-climbing geology student defies her imperious advisor to travel to the Nevada high desert, where a career-defining discovery and an unexpected friendship with a young cattle rancher force her to make life-altering decisions. Unconformity is the story of a friendship tested in the American West, framed by geology, rock climbing, land rights, exploitation in academia, and the climate crisis.
Join us for a post-film moderated conversation with writer and director Jonathan DiMaio ‘09.
