چکیده
We show how string breaking on the lattice, treated as a mixing effect, can be related to decay rates for heavy quark systems. We use this to make a preliminary calculation of the energy split at maximum mixing for static quarks in QCD from the decay rate for Υ(4S) → B ¯ B. We extend the calculation to achieve rough estimates for the contributions of channels involving B, B * , B s and B * s mesons to the width of the Υ(5S) .

After a brief discussion of the promise and limitations of the lattice technique, I review lattice QCD results for several quantities of phenomenological interest. These are: matrix elements for heavy-to-light meson decays, leptonic decay constants f B and f D , the parameters B B and B K for neutral B and K meson mixing respectively, the strong coupling constant, light quark masses and the lig...

We present high-statistics results for neutral B-meson mixing and heavy-light-meson leptonic decays in the quenched approximation from tadpole-improved clover actions at β = 6.0 and β = 6.2. We consider quantities such as BBd(s) , fDd(s) , fBd(s) and the full ∆B = 2 matrix elements as well as the corresponding SU(3)-breaking ratios. These quantities are important for determining the CKM matrix ...

Results from the Columbia lattice group study of the QCD finite temperature phase transition with dynamical domain wall fermions on 16 × 4 lattices are presented. These results include an investigation of the U(1) axial symmetry breaking above but close to the transition, the use of zero temperature calculations that set the scale at the transition and preliminary measurements close to the tran...

Recent developments in Quantum Chromodynamics (QCD) are reviewed on three major topics where nonper-turbative gluon excitations of the QCD vacuum and the physical properties of the confining flux play a central role: (1) New lattice results on the spectrum and wave functions of heavy QQgluon molecules, known as heavy hybrids, will be discussed. (2) Recent advances on the glueball spectrum in la...
