Event details
When the number of colors N tends to infinity, hadron observables of Quantum Chromo-Dynamics (QCD) are amenable to be expanded in series of 1/N. The large-N 1/N expansion of QCD is a theoretical tool with fundamental phenomenological implications. Unlike the usual perturbative expansion in the strong coupling, the 1/N expansion is fully non-perturbative. On general grounds, one needs lattice simulations to compute it from first principles. I will present a novel non-perturbative lattice determination of the meson spectrum of QCD in the large-N limit exploiting Eguchi-Kawai reduction. This is a general property of large-N gauge theories allowing the study of large-N dynamics in a volume-reduced one-point box.
About Particle Physics Theory seminars
The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
