Standard Model = particles + interactions

Why is QCD special ? Predicts existence of exotic matter, e.g. made from radiation (glueballs,hybrids) or novel plasmas. It builds from objects (quarks and gluons) that do not exist in a common sense, >95% mass comes from interactions! A single theory is responsible for phenomena at distance scales of the order of m as well as of the order 10 4 m. A possible template for physics beyond the Standard Model Quantum Chromodynamics (QCD) = physics of quarks and gluons

Ordinary matter made from 2 or 3 quarks but

small world ( m) of fast (v/c~1) particles exerting ~1T forces !!! Modern physics intuition can fail when applied to a world that is :

Theory and Phenomenology of Hadron production (Regge theory, lattice gauge, effective field theory,....) High statistics data (CLAS, BESIII...) Analysis Toolkit (AmpTools, GPU/CPU,..) New Physics Project goals:

First application: η → 3π η → 3π is the Golden channel to measure quark mass ratios (quark masses are fundamental unknowns, no direct measurement since quarks are confined) Pion interactions driven by residual hadron forces (the same forces which bind nucleons and can mask new resonances )

Project status: Development of theory for η → 3π has been completed. Several other reactions are well advanced. Experimental work at JLab on extraction of η decay data has advanced thanks to IUCRG Several papers are in various completion stages Proposal to NSF entitled:Physics at the Information Frontier:Extensible Computational Services for Discovery of New Particles was submitted (IU/GWU/JLab) We have established a global effort in amplitude analysis (Italy, Germany, Spain, Mexico,...) Planned for 2015: ATHOS Conf. in DC, Grad. Summer at IU, Hadron International Conf. at JLab
