Hot and dense matter out of quarks and gluons forms various status with external parameters such as the temperature, the chemical potential, the magnetic field, etc turned on and changed. The phase trasitions are characterized by realization of symmetries but the phase structure highly depends on the dynamical properties of matter. In this talk I will focus particularly on recent...

Observations of new charmonium(-like) and bottomonium(-like) states (sometimes refered to as "XYZ" states) at e+e- colliders have changed our picture of quarkonia systems as QCD bound states. Potential models with a linear confinement ansatz, which were able to predict many conventional states with an accuracy of ~1 MeV, absolutely fail in describing many of the new states. Symmetries play an...

The key for understanding the low energy QCD is chiral symmetry. This approximate symmetry allows for construction of a successful systematic approach to low energy QCD. The main application of this theory are processes involving light pseudoscalar mesons.
For example isospin breaking decay of eta mesoninto three pions provide precise constraints for ratios of the light quark masses and...
