Emergence of Hadron Mass and Structure

Visible matter is characterised by a single mass scale; namely, the proton mass. The proton’s existence and structure are supposed to be described quantum chromodynamics (QCD); yet, absent Higgs boson couplings, scale-invariant. Thus, if Standard Model truly part of theory Nature, then an emergent feature QCD; hadron (EHM) must provide basic link between observation. Nonperturbative tools necessary such connections made; in this context, we sketch recent progress application continuum Schwinger function methods array related problems particle physics. Special emphasis given three pillars EHM—namely, running gluon mass, process-independent effective charge, quark mass; their role stabilising measurable expressions diverse observables.
