Llanes Estrada, Felipe José ; Cotanch, Stephen R ; Szczepaniak, Adam P ; Swanson, Eric S | Springer | 2004-07We review theoretical calculations for the pseudoscalar vector meson hyperfine splitting with no open flavor and also report a many body field theoretical effort to assess the impact of chiral symmetry in the choice of effective potentials for r[...]texto impreso
Llanes Estrada, Felipe José ; Cotanch, Stephen R ; Szczepaniak, Adam P ; Swanson, Eric S | American Physical Soc | 2004-09Meson spin splittings are examined within an effective Coulomb gauge QCD Hamiltonian incorporating chiral symmetry and a transverse hyperfine interaction necessary for heavy quarks. For light and heavy quarkonium systems the pseudoscalar-vector [...]texto impreso
Llanes Estrada, Felipe José ; Bicudo, Pedro ; Cotanch, Stephen R | American Physical Soc | 2006-03-03We report an odderon Regge trajectory emerging from a field theoretical Coulomb gauge QCD model for the odd signature J(PC) (P=C=-1) glueball states. The trajectory intercept is clearly smaller than the Pomeron and even the omega trajectory's in[...]texto impreso
Utilizing an effective QCD Coulomb gauge Hamiltonian with linear confinement specified by lattice, we report a relativistic many-body calculation for the light exotic and charmed hybrid mesons. The Hamiltonian successfully describes both quark a[...]
