Uspekhi Fizicheskih Nauk, 1989
A review is given of experimental data on oscillations. Basic theoretical concepts are discussed and an analogy with oscillations is noted. A detailed analysis is given of experimental searchesfor oscillations with particular attention devoted to the ARGUS data, which reveal mixing with r = Γ( → → X')/Γ( → X) = 0.21±0.08. The consequences of large

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.

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.

Inference: International Review of Science, 2017
Particle physicist Joaquim Matias analyzes recent results from the Large Hadron Collider—in particular, rare decays of B-mesons that suggest the violation of leptonic universality—for evidence of New Physics.

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.

Reports on Progress in Physics, 1989
In this report I discuss the physics of B mesons which were first observed directly in 1986 through their full reconstruction. Emphasis is put on the experimental results on exclusive and inclusive B decays obtained since then by the e"e- experiments ARGUS at DESY and CLEO at Cornell.

Modern Physics Letters A, 1989
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.
