"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…
The form factor of the pion in "point-form" of relativistic dynamics revisited
A. Amghar, B. Desplanques, L. Theussl
The electromagnetic form factor of the pion is calculated in the "point-form" of relativistic quantum mechanics using simple, phenomenological wave functions. It is found that 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…
More about the comparison of local and non-local NN interaction models
A. Amghar, B. Desplanques
The effect of non-locality in the NN interaction with an off-energy shell character has been studied in the past in relation with the possibility that some models could be approxim…
Comparison of Form Factors Calculated with Different Expressions for the Boost Transformation
A. Amghar, B. Desplanques, L. Theussl
The effect of different boost expressions is considered for the calculation of the ground-state form factor of a two-body system made of scalar particles interacting via the exchan…
