Parity violation and the nature of charges
B. Desplanques
The origin of parity violation in physics is still unknown. At the present time, it is introduced in the theory by requiring that the SU(2) subgroup entering the description of int…
"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…
Form factors in the "point form" of relativistic quantum mechanics: single and two-particle currents
B. Desplanques, L. Theussl
Electromagnetic and Lorentz-scalar form factors are calculated for a bound system of two spin-less particles exchanging a zero-mass scalar particle. Different approaches are consid…
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…
