The Evidence for a Pentaquark Signal and Kinematic Reflections
A. R. Dzierba, D. Krop, M. Swat +2
Several recent experiments have reported evidence for a narrow baryon resonance with positive strangeness () at a mass of 1.54 GeV/. Baryons with cannot be convent…
The low lying glueball spectrum
Adam P. Szczepaniak, Eric S. Swanson
The complete low-lying positive charge conjugation glueball spectrum is obtained from QCD. The formalism relies on the construction of an efficient quasiparticle gluon basis for Ha…
K Kbar photoproduction and S-P wave interference
Lukasz Bibrzycki, Leonard Lesniak, Adam P. Szczepaniak
Results of a new analysis of the photoproduction at two photon energies and with a particular emphasis on the -wave production are presented.…
Confinement and gluon propagator in Coulomb gauge QCD
Adam P. Szczepaniak
We consider the effects of the Faddeev-Popov determinant in the Coulomb gauge on the confinement properties of the QCD vacuum. We show that the the determinant is needed to regular…
Separation of Soft and Hard Physics in Deeply Virtual Compton Scattering
A. Gardestig, A. P. Szczepaniak, J. T. Londergan
A model for deeply virtual Compton scattering, based on analytical light-cone hadron wave functions is presented and studied at energies currently accessible at Jefferson Laborator…
Description of the resonance as the atom
Adam P. Szczepaniak
We discuss the possibility that the recently reported resonance in the spectrum can be described in terms of residual interactions.
Study of the and spectra and interpetation of possible exotic mesons
Adam P. Szczepaniak, Maciej Swat, Alex R. Dzierba +1
We discuss a coupled channel analysis of the and systems produced in interactions at 18 GeV/. We show that known resonances, together with residual s…
A Study of the ηπ^{0} Spectrum and Search for a J^{PC} = 1^{-+} Exotic Meson
A. R. Dzierba, J. Gunter, S. Ichiriu +12
A partial wave analysis (PWA) of the of the system (where ) produced in the charge exchange reaction at an incident momentum of 18 GeV is presen…
