The ability of future e^+e^- linear colliders to study the supersymmetric Higgs sector is examined. The effects of the radiative corrections are included. A global analysis is given for the production cross sections of the neutral Higgs bosons over the full parameter space of the Higgs sector, which clarifies the integrated luminosity necessary for the detection of the neutral Higgs bosons. The branching ratios of the three neutral Higgs bosons are also computed.

In the framework of the minimal supersymmetric standard model (MSSM) and the R-parity breaking model (RBM) we investigate production processes of the scalar top (stop) at HERA energies. These models are characterized possibly by lighter stop mass than the top quark and the other squarks. It is shown that in the MSSM the stop pair production via boson-gluon fusion gives viable cross section and the most serious background ep → ecc^^-X could be suppressed by appropriate kinematical cuts. We also show that in the RBM the stop is singly produced in the neutral current processes and we have a clear signal as a sharp peak in the x distribution.

Top quark decay in the Minimal Supersymmetric Model is studied. Possible decays are t → bW^+,t^^〜_1z^^〜_k,b^^〜w^^〜^+_1, t^^〜_1g^^〜 and bH^+. We find that the supersymmetric modes can overwhelmingly dominate the t decay in a wide and still allowed range of the model parameters and that they have very distinctive signatures compared to the standard mode bW^+. This could shed a crucial impact on t quark search.

Phenomenology of the Kobayashi-Maskawa matrix and quark mass matrices is reviewed in relation to works in our research group "BDK91" (B, D, K meson physics and quark mixing and CP violation). The talk is organized as follows: 1. Why we interest in the KM matrix? 2. How many parameters? 3. Parametrization of the KM matrix 4. Experimental status of the KM matrix and quark masses 5. Empirical relations for |V_<ij>| 6. Morphology of quark mass matrices

Semileptonic decays B^^- → D^<(*)>lv^^- and D^^- → K^<(*)>lv^^- are analyzed in the heavy quark effective theory with leading 1/m_Q corrections. In particular, a significant role of 1/m_s corrections for the process D^^- → K^^<(*)>lv^^- is discussed.

We derived an asymptotic formula for q-6j symbol. This is a generalization of the former work by Ponzano and Regge. We find the term which should be related to the cosmological constant term in three-dimensional gravity. The physical implication of this fact is discussed. We also review some preceding works briefly. This note is based on the work with Dr. Mizoguchi [1].

The Ward identities of the Liouville gravity coupled to the minimal conformal matter are investigated. We introduce the pseudo-null fields and the generalize equations of motion, which are classified into series of the Liouville charges. These series have something to do with the W and Virasoro constraints. The pseudonull fields have non-trivial contributions at the boundaries of the moduli space. We explicitly evaluate the several boundary contributions. Then the structures like the W and the Virasoro constraints appearing in the topological and the matrix methods are realized. Although our Ward identities have some different features from the other methods, the solutions of the identities are consistent to the matrix model results.
