Book Description
In lattice QCD, obtaining properties of heavy-light mesons has been easier said than done. Focusing on the B meson's decay constant, it is argued that towards the end of 1997 the last obstacles were removed, at least in the quenched approximation. These developments, which resulted from a fuller understanding and implementation of ideas in effective field theory, bode well for current studies of neutral meson mixing and of semileptonic decays.

Book Description
This volume is a unique report on the frontiers of subnuclear physics presented by global specialists in a clear and rigorous style.The question of Lattice QCD is presented by R D Kenway, and that of Quark-Gluon Plasma Physics by F Karsch. Quantum Field theory is discussed by R G Dijkgraff, and the status of Local Supersymmetry by M J Duff. Detailed analysis of Supersymmetry in Nuclei is made by F Iachello, and that of Inflation, Dark Matter and Dark Energy by E W Kolb. Compactified dimensions are outlined by I Antoniadis, Horizons in the quantization of the gravitational force by Nobel Laureate G 't Hooft, as also are Neutrino Oscillations by G Fogli and Fundamental Constants by H Fritzsch. The experimental data from BNL and Babar are presented by T W Ludlum and M A Giorgi, those from Fermilab and Hera by Parke and G Wolf. The status at CERN is given by L Maiani for the LHC and by W-D Schlatter for the non-LHC experiments. Highlights from Gran Sasso are presented by A Bettini. This volume also contains reports by a selected group of “new talents” on various topics in the field of subnuclear physics.The proceedings have been selected for coverage in:• Index to Scientific & Technical Proceedings® (ISTP® / ISI Proceedings)• Index to Scientific & Technical Proceedings (ISTP CDROM version / ISI Proceedings)• CC Proceedings — Engineering & Physical Sciences

Book Description
Recent measurements of the branching fraction for D{sub s} → lv disagree with the Standard Model expectation, which relies on calculations of f{sub D{sub s}} from lattice QCD. This paper uses recent preliminary measurements from CLEO and a new preliminary lattice-QCD result from this conference to update the significance of the discrepancy. The 'f{sub D{sub s}} puzzle' stands now at 3.5[sigma], with [sigma] predominantly from the statistical uncertainty of the experiments. New physics scenarios that could solve the puzzle would also lead to non-Standard amplitudes mediating the semileptonic decays D → Klv. This paper shows where the new amplitudes enter the differential rate and outlines where lattice QCD calculations are needed to confront recent and forthcoming measurements.

Book Description
The book deals with an introductory idea of Leptonic and semileptonic decay of Heavy-Light mesons. It also highlight the application of a specific QCD potential model in this area of physics. Specifically, it also addresses the application of quantum mechanical perturbation method and explicitly the Dalagarno method of perturbation in this context. The necessity of modification of the model within the constraints of QCD and the model itself is explained and also improved accordingly. Out of the five chapters, the second and third chapters address the leptonic decay of B and D mesons whereas in the last two chapters, the study of semileptonic decay in terms of the universal form factor, Isgur-Wise function is well explained.
