Seminar

Speakers: Chris Gordon (University of Canterbury) If QCD axion dark matter formed post-inflation, axion miniclusters emerged from isocurvature fluctuations and later merged hierarchically into minihalos. These minihalos, potentially disrupted by stellar encounters in the Milky Way, affect axion detectability. We extend prior analyses by more accurately incorporating multiple stellar encounters and dynamical relaxation timescales, simulating ... Read more

Speakers: Xiaochuan Lu (University of California, San Diego) Effective Field Theories (EFTs) have wide reaching applications in particle physics of and beyond the Standard Model (BSM). They also serve as the foundation for our modern understanding of renormalization in Quantum Field Theories. In this talk, I will discuss a few crucial aspects of EFTs, including ... Read more

Speakers: Brian Henning (Kavli Institute for Theoretical Physics/UCSB) High-energy physics experiments measure distributions of relativistic events across phase space, yet traditionally phase space has served merely as a calculational backdrop. In this seminar, I propose a paradigm shift: viewing phase space as a dynamic, geometric entity deeply entwined with the underlying physics. By treating phase ... Read more

Speakers: Gilly Elor (University of Texas, Austin) I will present an overview of my short and long term research plans. I will begin by presenting more background behind my colloquium topic: mesogenesis. The goal of my 4-year mesogenesis research plan is to enable the discovery (or complete exclusion) of all variations of this mechanism. I ... Read more

Speakers: Matthew Low (University of Pittsburgh) The treatment of outgoing particles at high-energy colliders as qubits in a quantum system has recently enabled the application of quantum information tools to high-energy physics. This began with the study of quantum entanglement between a top quark and an anti-top quark, which has already been measured in experiments ... Read more
