Positivity Bounds on Massive Higher Spins

This conference talk by Brando Bellazzini from IPhT-CEA Saclay explores positivity bounds on massive higher spins within the context of strongly interacting Quantum Field Theory (QFT). Dive into the theoretical framework where the strong nuclear force meets Quantum Chromodynamics (QCD), examining how Yang-Mills theory transitions from asymptotic freedom to strong coupling at long distances. Learn about quark confinement and chiral symmetry breaking phenomena supported by experimental and lattice QCD evidence. The presentation connects lattice and continuum approaches to QFT, touching on Euclidean and Hamiltonian approaches to lattice field theory, their symmetries, and emerging connections with quantum simulation and computation. Explore string-theoretic approaches to confining flux tubes, dynamics in Minkowski spacetime, lower-dimensional QCD models, and their relationship with recent formal QFT developments including generalized symmetries.
