"Point-form" estimate of the pion form factor revisited
B. Desplanques, A. Amghar, L. Theussl
The pion form factor calculation in the ``point-form'' of relativistic quantum mechanics is re-considered. Particular attention is given to the relation between the momentum of the…

Comparison of Different Boost Transformations for the Calculation of Form Factors in Relativistic Quantum Mechanics
L. Theussl, A. Amghar, B. Desplanques +1
The effect of different boost expressions, pertinent to the instant, front and point forms of relativistic quantum mechanics, is considered for the calculation of the ground-state…

Nucleon-nucleon interaction models and non-locality
B. Desplanques, A. Amghar
The effect of non-locality in the NN interaction models is examined. It is shown that this feature can explain differences in predictions made from models evidencing a difference w…
