Hadronic resonances from lattice QCD

Dr. Fernando Romero-Lopez(MIT) The majority of known hadrons in the low-energy QCD spectrum are resonances observed in multi-particle scattering processes. First-principles determinations of the properties of these unstable hadrons are a crucial goal in lattice QCD calculations. Significant progress has been made in developing, implementing, and applying theoretical tools that connect finite-volume lattice QCD quantities to scattering amplitudes, enabling determination of masses and widths of various hadronic resonances. In this talk, I will discuss recent advances in the study of meson-baryon resonances, including the Delta(1232) and Lambda(1405) resonances, as well as three-hadron resonances using lattice QCD
