Assuming Coulomb-like as well as confining scalar potential, we have solved Shrödinger equation perturbatively in 1/mQ with a heavy quark mass mQ. The lowest order equation is examined carefully. Mass levels are fitted with experimental data for D/B mesons at each level of perturbation. Meson wave functions obtained thereby can be used to calculate ordinary form factors as well as Isgur-Wise fu...

These lectures introduce some of the basic notions of effective field theories, as used in particle physics. The topics discussed are the ∆S = 1 and ∆S = 2 weak interactions, and chiral perturbation theory as applied to mesons, baryons, and hadrons containing heavy quarks.

I give a brief review of final state interactions in meson decays. I describe possible effects of FSI in K, D and B systems, paying particular attention to the description of the heavy meson decays. Available theoretical methods for dealing with the effects of FSI are discussed.

Operating just once with the naive Foldy-Wouthuysen-Tani transformation on the relativistic Fermi-Yang equation for Qq̄ bound states described by the semi-relativistic Hamiltonian which includes Coulomb-like as well as confining scalar potentials, we have calculated heavy meson mass spectra of D and B together with higher spin states. Based on the formulation recently proposed, their masses and ...
