Reports on Progress in Physics, 1986
The author discusses the physics of the hadrons containing charmed, bottom and top quarks. The emphasis is on the most recent experimental results from the e+e- storage rings in the 3-12 GeV range of centre-of-mass energy: SPEAR at SLAC, DORIS at DESY, and the Cornell Electron Storage Ring CESR.

Physics of heavy-quark production in quantum chromodynamics
Physical Review D, 1987For very heavy quark masses, QCD predicts that the inclusive hadronic production of heavy quarks is governed by quark and gluon hard-scattering subprocesses. On general grounds, one expects corrections of order \ensuremath{\mu}/${M}_{Q}$, where \ensuremath{\mu}\ensuremath{\sim}300 MeV and ${M}_{Q}$ is the heavy-quark mass. At the charm mass scale, such

Nuclear Physics B - Proceedings Supplements, 1992
Abstract A brief overview of the anticipated heavy quark physics at HERA is given. The topics discussed include heavy quark photo- and leptoproduction cross sections at HERA calculated in the context of perturbative QCD, various mechanisms of J / ϕ -leptoproduction and their rates, determination of the gluon density of the proton using open and ...

Nuclear Physics B - Proceedings Supplements, 1999
Abstract In this report we review the latest results on heavy quark physics reached at HERA by the H1 and ZEUS collaborations. We start from the open charm measurements performed both in photoproduction and in deep inelastic scattering regime following with bound charm physics.

Strong CP in Heavy Quark Physics
Communications in Theoretical Physics, 1991We argue that strong CP phase should be shifted to b and t quark masses due to the requirement of vacuum stability. The strong CP problem in low energy sector thus disappears. We predict large CP violation in electric dipole moment of W and heavy quarks.

Heavy Quark Physics on Large Lattices
2005We describe our recently initiated project for the non-perturbative study of heavy quark systems in quenched lattice QCD. Motivated by the desire to avoid additional approximations, we work on fine lattices which are large in terms of the number of lattice points.

Aspects of Heavy Quark Physics
1998We discuss the use of two QCD based effective field theories in determining parameters of the standard model. Heavy Quark Effective theory provides a framework for studying the weak decays of the B meson. We calculate the B → Xclv decay rate to second nonvanishing order in the HQET expansion and compare the theoretical prediction to experimental data ...

1997
Heavy Quark Effective Theory (HQET) is reviewed and applied to extracting the fundamental parameters of the Standard Model from experimental data. The main focus is on precision measurements of the Cabibbo-Kobayashi-Maskawa matrix element |Vcb|, and the charm and bottom quark masses mc and mb.

Heavy Quark Physics//The Potential of BTeV
AIP Conference Proceedings, 2003The experimental layout of the BTeV experiment at Fermilab is described. This includes a brief overview of the various detector systems that make up the BTeV spectrometer. The primary goal of the experiment is to look for physics beyond the Standard Model(SM) by performing precise measurements of the Cabibbo‐Kobayashi‐Maskawa matrix parameters to look ...
