AbstractThe concepts of compositeness and symmetry on the microstructure of matter have had a significant influence on the quest for the origin of particles and the universe. The studies on the property and phenomenology of hadrons as composite particles have led many insights and discoveries in particle physics, such as flavor symmetry, chiral symmetry, PCAC, strong interaction, dynamical symmetry breaking, indirect and direct CP violations, quark model from three flavors to three families, chiral dynamical model, quantum chromodynamics, quark confinement. I briefly present some interesting progresses and insights made in our group based on compositeness and symmetry. It can be seen that both the indirect and direct CP symmetry violation in kaon decays as well as the isospin Delta I = 1/2 selection rule can simultaneously be explained in the standard model with the Kobayashi-Maskawa CP-violating phase and the chiral dynamic loop effect. We present a brief description on the symmetry-preserving loop regularization (LORE) method which is realized in four dimensional space-time. The LORE method introduces two energy scales and maintains the initial divergence behavior, which overcomes some shortages in other regularization schemes. A chiral dynamical model of QCD can be derived by using the LORE method to understand the spontaneous chiral symmetry breaking via the dynamically generated composite Higgs potential, which can provide a consistent prediction for the mass spectra of both the nonet scalar and pseudoscalar ground state mesons. By extending such a model to a chiral thermodynamic model with the closed-time-path Green function approach, it enables us to characterize the critical behavior of QCD and the restoration of chiral symmetry breaking.
