Constituent-quark model with pionic contributions: electromagnetic transition
Ju-Hyun Jung, Wolfgang Schweiger, Elmar P. Biernat
We report on ongoing work to determine the pion-cloud contribution to the electromagnetic transition form factors. The starting point is an spin-flavor symm…
Singularity-free two-body equation with confining interactions in momentum space
Alfred Stadler, Sofia Leitão, M. T. Peña +1
We are developing a covariant model for all mesons that can be described as quark-antiquark bound states in the framework of the Covariant Spectator Theory (CST) in Minkowski space…
Charged and neutral pion production in the S-matrix approach
V. Malafaia, M. T. Pena, Ch. Elster +1
The S-matrix approach is used to calculate charged as well as neutral pion production reactions from NN scattering, with the same set of underlying processes and interactions. The…
Pion re-scattering operator in the S-matrix approach
V. Malafaia, J. Adam, M. T. Pena
The pion re-scattering operator for pion production, derived recently in time-ordered perturbation theory, is compared with the one following from the simple S-matrix construction.…
