Coulomb energy and gluon distribution in the presence of static sources
Adam P. Szczepaniak, Pawel Krupinski
We compute the energy of the ground state and a low lying excitation of the gluonic field in the presence of static quark -anti-quark ($\qq$) sources. We show that for separation b…
A partial wave analysis of the and systems and the search for a meson
A. R. Dzierba, R. Mitchell, E. Scott +12
A partial wave analysis (PWA) of the and systems produced in the reaction at 18 GeV/ was carried out using an \emph{isobar} model…
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.…
An exactly solvable limit of low energy QCD
Peter O. Hess, Adam P. Szczepaniak
Starting from the QCD Hamiltonian, we derive a schematic Hamiltonian for low energy quark dynamics with quarks restricted to the lowest s-level. The resulting eigenvalue problem ca…
A search for J^{PC}=1^{-+} exotic mesons in the pi- pi- pi+ and pi- pi0 pi0 systems
A. R. Dzierba, R. Mitchell, A. P. Szczepaniak +2
A partial wave analysis (PWA) of the pi-pi-pi+ and pi-pi0pi0 systems produced in the reaction pi- p -> (3pi)-p at 18 GeV/c was carried out using an isobar model assumption. This an…
Final State Interactions in Decays of the Exotic Meson
Nikodem J. Poplawski, Adam P. Szczepaniak, J. T. Londergan
We analyze the role of final state interactions in decay of the lighest exotic meson, with $J^{PC}=1^{-+}. We use the relativistic Lippmann-Schwinger equation for two couple…
