Instantaneous Bethe-Salpeter Equation with Exact Propagators
Wolfgang Lucha, F. F. Schoberl
Consequent application of the instantaneous approximation to both the interaction and all propagators of the bound-state constituents allows us to forge, within the framework of th…
Facets of the spinless Salpeter equation
Wolfgang Lucha, F. F. Schoberl
The spinless Salpeter equation represents the simplest and most straightforward generalization of the Schroedinger equation of standard nonrelativistic quantum theory towards the i…
Instantaneous Bethe-Salpeter Equation: (Semi-)Analytical Solution
Wolfgang Lucha, Khin Maung Maung, F. F. Schoberl
The Bethe-Salpeter equation for bound states of a fermion-antifermion pair in the instantaneous approximation for the involved interaction kernel is converted into an equivalent ma…
Comment on "Calculation of the Quarkonium Spectrum and m(b), m(c) to Order alpha(s)**4"
Wolfgang Lucha, F. F. Schoberl
A recent determination of the mass of the b quark, based exclusively on quantum chromodynamics (by avoiding strictly to introduce any phenomenological interaction potential of nonp…
Spinless Salpeter Equation: Analytic Results
Wolfgang Lucha, Franz F. Sch"oberl
The spinless Salpeter equation is the combination of relativistic kinematics with some static interaction potential. The nonlocal nature of the Hamiltonian resulting from this appr…
Effective Potential Models for Hadrons
Wolfgang Lucha, Franz F. Schöberl
The aim of these lectures is to give a self-contained introduction to nonrelativistic potential models, to their formulation as well as to their possible applications. At the price…
