Event details
Charm baryon spectroscopy has seen renewed interest following LHCb’s 2026 observations confirming the mass of the doubly charmed cascade (dcc) and making the first-ever observation of the doubly charmed omega baryon (scc), completing the SU(4) multiplet of ground-state spin-1/2 baryons. At low energies, hadron properties cannot be determined using analytic or perturbative approaches to quantum chromodynamics (QCD). Instead, we utilise a first-principles numerical approach to QCD known as lattice QCD, providing the theoretical calculations necessary to complement LHCb’s active charm physics programme. We study the properties of low-lying spin-0 mesons and spin-1/2 baryons containing up, down, strange, and charm quarks, and investigate the contributions of strong isospin breaking and state mixing to hadron masses.
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..
