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: Xiaochuan Lu (University of California, San Diego) Symmetry principles are extremely powerful tools for understanding the properties of physics systems generally, including particle physics. The ideas of symmetry are critical for establishing the Standard Model of particle physics and will guide us towards future discoveries. In this talk, I will explain how to make ... 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: Brian Henning (Kavli Institute for Theoretical Physics/UCSB) Strong-coupling phenomena—ranging from exotic meson structures to the rich QCD phase diagram impacting heavy ion collisions, neutron stars, and early-universe transitions—pose challenges that have long eluded our conventional perturbative and lattice tools. In this colloquium, I will present a novel nonperturbative approach based on Hamiltonian truncation (HT), ... Read more
