Standard Model particles interactions

Quantum Chromodynamics (QCD) physics of quarks
and gluons
Why is QCD special ?
  • A single theory is responsible for phenomena
    at distance scales of the order of 10-15m as
    well as of the order 104m.
  • It builds from objects (quarks and gluons) that
    do not exist in a common sense, gt95 mass comes
    from interactions!
  • Predicts existence of exotic matter, e.g.
    made from radiation (glueballs,hybrids) or novel
    plasmas.
  • A possible template for physics beyond the
    Standard Model

Ordinary matter made from 2 or 3 quarks but
5
Modern physics intuition can fail when applied
to a world that is
small world (10-15m) of fast (v/c1) particles
exerting 1T forces !!!

Project goals
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

First application ? ? 3p
? ? 3p 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 )
10
Project status
Development of theory for ? ? 3p has been
completed. Several other reactions are well
advanced.
Experimental work at JLab on extraction of ?
decay data has advanced thanks to IUCRG
Several papers are in various completion stages
Proposal to NSF entitledPhysics at the
Information FrontierExtensible 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
