Presented By: Leinweber Institute for Theoretical Physics
HET Brown Bag Seminar | Maximizing the Interaction Strength
Miguel Correia (McGill)
QCD remains intractable in the high-energy soft regime, where all standard methods break down. This regime governs total hadronic cross-sections, which have long been observed to grow with energy, a phenomenon that is still very poorly understood today. In this talk, I will argue that the modern S-matrix bootstrap provides a systematic way to tackle this regime of QCD. I will derive an upper bound on the total cross-section at finite energy and present the strongest interacting amplitude that the bootstrap outputs. I will compare these results with proton–proton experimental data.
