Many-Body Approach to Mesons, Hybrids and Glueballs
Stephen R. Cotanch, Felipe J. Llanes-Estrada
We represent QCD at the hadronic scale by means of an effective Hamiltonian, H, formulated in the Coulomb gauge. As in the Nambu-Jona-Lasinio model, chiral symmetry is dynamically…
Hamiltonian renormalization for bound state problem in gluodynamics
Elena Gubankova, Chueng-Ryong Ji, Stephen R. Cotanch
The systematic approach to study bound states in gluodynamics is presented. The method utilizes flow equations together with low-energy phenomenology, that provides the perturbativ…
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…
