Particle physics makes progress in three Frontiers: (1) High Energy Frontier, (2) High Intensity Frontier, and (3) High Precision Frontier. Category (1) will be dominated by the SSC and LHC experiments in the next decade and (3) by precise measurements of the (g−2)μ and sin2θw.

AIP Conference Proceedings, 1988
The third generation of quarks, anticipated in 1973 by Kobayashi and Maskawa as one of the possibilities to explain CP violation of the Ko‐meson system within the framework of the Standard Model and in 1975 by the discovery of the third generation of leptons, was found at FNAL in 1977.

B meson decays into charmless pseudoscalar scalar mesons
AIP Conference Proceedings, 2007The nonleptonic weak decays of meson B into a scalar and pseudoscalar meson are studied. The scalar mesons under consideration are σ (or f0(600)), f0(980), a0(980) and K0*(1430). We calculate the Branching ratios in the Naive Factorization approximation.

Abstract I review the experimental information on weak decays of B mesons. The emphasis is on the measurements which determine the Cabibbo-Kobayashi-Maskawa matrix elements.

The lifetime of hadrons containing b-quark has been the subject of extensive experimental work and theoretical speculation; its importance is due to implications on some of the fundamental parameters of the Standard Model, such as the top quark mass and the mixing angles.

Exclusive semileptonic decays ofBmesons into light mesons
Physical Review D, 1994Using heavy quark effective field theory, exponentiation of Sudakov double logarithms, and perturbative factorization theorems for exclusive processes, we calculate the amplitude for the semileptonic decay of mesons with a single, very heavy quark into \ensuremath{\pi} and \ensuremath{\rho} for a large hadronic recoil momentum.

We have studied production of B* mesons at the ?(5S), detecting the quasimonochromatic photon from decay to the ground state. The observed signal is expected to be doppler broadened because of the motion of the B* d,u mesons from ?(5S) decays. The observed broadening is however considerably smaller than expected, and consistent with copious production ...

Semileptonic decays of B meson into charmed meson
AIP Conference Proceedings, 1989Recent results on semileptonic decays of B meson into charmed meson using the CLEO detector at CESR are summarized. Ratios of the inclusive semileptonic branching fractions, B(B−→D0Xl−ν), B(B0→D+Xl−νXl−ν, and B(B0→D*+ average B meson semileptonic branching fraction are reported. The branching fractions of the exclusive final states, B−→D0l−ν, B−→D*0l−ν,

SU(6)Analysis of Mesonic of B-Mesons
Communications in Theoretical Physics, 1990The SU(6) symmetry of strong interactions among light quarks is used to analyse two-body mesonic decays of B-mesons based on the Hamiltonian proposed by He-McKellar-Wu.
