S-P wave interference in the K+K- photoproduction on hydrogen
L. Bibrzycki, L. Lesniak, A. P. Szczepaniak
We have studied the partial wave interference effects to obtain a new information about the contribution of the S-wave to the cross section of the K+K- photoproduction on hydrogen.…
Renormalized Effective Hamiltonian Approach to QCD
D. G. Robertson, E. S. Swanson, A. P. Szczepaniak +2
Continuing our previous QCD Hamiltonian studies in the gluonic and quark sectors, we describe a new renormalization procedure which generates an effective Hamiltonian. The formulat…
Covariant Variable Front Quark Model
A. Szczepaniak, C-R. Ji, S. R. Cotanch
We study the implications of Lorentz symmetry for hadronic structure by formulating a manifestly covariant constituent quark model and find full covariance for any Lorentz transfor…
Light Quark Energy Distribution in Heavy Quark Symmetry
A. Szczepaniak, C-R. Ji, S. R. Cotanch
Using heavy quark symmetry we construct an energy sum rule relating the form factor of a heavy flavored meson to the light quark energy distribution. We find that the curren…
