Abstract:
I explore the essential role that kaons have played in revealing the nature of the micro-physics world of elementary particle physics.

Abstract:
Electric and magnetic dipole moments of spinning solitons will be discussed. Effects of the topological term can be calculated non-perturbatively in the Seiberg-Witten model.

Abstract:
I will review lattice methods to investigate strongly interacting gauge theories in the theory space beyond the Standard Model.

Abstract:
I describe the recent results in the theory of the quantum Hall effect based on the magnetic catalysis phenomenon.

Abstract:
In this talk, I will discuss constraints on models of physics beyond the Standard Model from the new limits on supersymmetry and other models that have been placed by the LHC data, and consider where we should be looking for new physics at the next stage of the LHC program.

Abstract:
After some historical background, both the low lying scalar and pseudoscalar meson multiplets are studied in some detail. This raises the well known questions of whether the scalars are quark anti-quark states or two quark - two anti-quark states and what this has to say concerning the quark structure of their chiral partners, the pseudoscalars. A "toy model" is presented which allows both scalars and pseudoscalars to have quark anti-quark as well two quark two antiquark components. The masses as well as the quark structures of all particles are predicted in terms of a few parameters. The possibility of testing some aspects of the model in terms of experimental data on the semi-leptonic decays of charmed mesons is demonstrated.

Abstract:
I will discuss some efforts to understand one of the current puzzles involving quarks --- the top quark asymmetry at the Tevatron --- through observations at the Tevatron and Large Hadron Collider. Then I will turn to the possibility of observable hidden sectors ("hidden valleys") and how one might search for them now and in the near future.

Abstract:
I will introduce Professor Shoichi Sakata and his glorious achievements by using various documents archived in the Sakata Memorial Archival Library (SMAL).

Abstract:
The 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. Here I briefly present some interesting progresses and insights based on the compositeness and symmetry. It is shown that both the indirect and direct CP violation in kaon decays as well as the isospin ΔI = 1/2 selection rule can simultaneously be explained in the standard model with the Kobayashi-Maskawa CP-violating phase and the chiral dynamic quantum loop effect. It is found that a chiral dynamical model of QCD can be derived by using the loop regularization 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. Such a model can be extended to obtain a chiral thermodynamic model by the closed-time-path Green function approach and to characterize the critical behavior of QCD and the restoration of symmetry breaking. It is observed that a realistic predictive AdS/QCD model can be built to understand both the chiral symmetry breaking and linear confinement of QCD, which results in a consistent prediction for the mass spectra of all light resonance scalar, pseudoscalar, vector and axial-vector mesons. The QCD phase transition and critical temperature are investigated based on such a realistic holographic AdS/QCD model with finite temperature. It is shown that the SO(3) gauge family symmetry may lead to the explanation on the small neutrino masses and large mixing.

Abstract:
In 1955 Sakata proposed a composite model, the Sakata model, which triggered the last revolution, paving the way to the quark model and eventually to the Standard Model. Now facing a new revolutionary era of LHC, we discuss composite approach to the physics beyond the Standard Model. The key issue is the Origin of Mass. Instead of the elementary Higgs boson we discuss composite Higgs in various models with large anomalous dimension, which we proposed in the past quarter century: Walking Technicolor, Strong ETC Technicolor and the Top Quark Condensate. The walking technicolor has an approximate scale (conformal) symmetry due to almost non-running (``walking'') coupling constant, which leads to a large anomalous dimension near unity and predicts a techni-dilaton, composite pseudo Nambu-Goldstone boson of the scale symmetry, as a remnant of the approximate scale symmetry. The techni-dilaton will have mass about 600 GeV in the typical model, which may be observed at LHC. We also discuss the related composite gauge boson based on the hidden local symmetry.

Abstract:
I will explain why the baryon asymmetry in the universe is related to the small neutrino masses.

Abstract:
Perturbative series are expected to diverge in high orders. In QCD case, in particular, such divergencent series are to be supplemented by power-like corrections which are exponentially small in the inverse running coupling and make the total answer unique. Existing examples of long perturbative expansions do not exhibit however such divergences so far. Instead, a pattern of geometrical series might emerge. Moreover the long perturbative expansions appear to be rather dual to the power-like corrections which are effective only if added to relatively short perturbative expansions.
