SYUM 1.4: Plenary Talk

Hadrons and Nuclei: Mass without Higgs — •Ulf-G. Meißner — Universität Bonn & Forschungszentrum Jülich

This talk concerns the generation of the masses of hadrons and nuclei that make up most of the visible matter in the universe. I discuss how the strong interactions generate the mass of hadrons made of light quark through gluonic interactions and the role of the small quark masses. The ab initio calculation of nuclei and in particular the spectrum of carbon-12 is discussed. I show how the generation of carbon and oxygen is modified when the quark masses undergo small variations. The implications for the anthropic principle are also laid out.
