Bound States in the LFD Yukawa Model
M. van Iersel, B. L. G. Bakker
Our purpose is to calculate relativistic bound states in a quantum filed theoretical approach. We work in the Yukawa model and first calculate the bound-state equation in the ladde…
Vector Anomaly Revisited in the Anomalous Magnetic Moment of Bosons
Bernard L. G. Bakker, Cheung-Ryong Ji
In the calculation of the anomalous magnetic moment of bosons, we discuss vector anomalies occuring in the fermion loop that spoil the predictive power of the theory. While…
Techniques for solving bound state problems
M. van Iersel, C. F. M. van der Burgh, B. L. G. Bakker
We have used different methods to obtain the bound states of a Hamiltonian of a relativistic two scalar particle system in a local potential. The potentials we are interested in ar…
The scalar field-theoretical Coulomb problem
N. E. Ligterink, B. L. G. Bakker
We analyze the fully relativistic, field-theoretical treatment of the scalar Coulomb problem. We work in a truncated Hilbert-Fock space containing the two-constituent states and th…
Equivalence of Covariant and Light-Front Perturbation Theory
N. C. J. Schoonderwoerd, B. L. G. Bakker
Light-Front Field Theory (LFFT) is a good candidate to describe bound states. In LFFT covariance is non-manifest. Burkardt and Langnau claim that, even for scattering amplitudes, r…
