Nucleon resonances in polarized omega photoproduction

Yongseok Oh, Alexander I. Titov, T. -S. H. Lee

The role of the nucleon resonances ( $N^{*}$ ) in $ω$ photoproduction is investigated by using the resonance parameters predicted by Capstick and Roberts. The contributions from the nu…

J/psi absorption by pi and rho mesons in a meson exchange model with anomalous parity interactions

Yongseok Oh, Taesoo Song, Su Houng Lee

We reanalyze the dissociation process of the $J / ψ$ by $π$ and $ρ$ mesons into $D + D ˉ$ , $D^{*} + D ˉ$ , $D + D ˉ^{*}$ , and $D^{*} + D ˉ^{*}$ within a meson exchange model.…

The Relativistic N-body Problem in a Separable Two-Body Basis

Cheuk-Yin Wong, Horace W. Crater

We use Dirac's constraint dynamics to obtain a Hamiltonian formulation of the relativistic N-body problem in a separable two-body basis in which the particles interact pair-wise th…

Gluonic Correlations in Matter

Su Houng Lee, Ismail Zahed

We derive the analogue of the QCD low energy theorems for the scalar and pseudoscalar gluonic correlators in nuclear matter. We find that the scalar correlations are depleted while…

Pertinent Dirac structure for QCD sum rules of meson-baryon coupling constants

Takumi Doi, Hungchong Kim, Makoto Oka

Using general baryon interpolating fields $J_{B}$ for $B = N, Ξ, Σ,$ without derivative, we study QCD sum rules for meson-baryon couplings and their dependence on Dirac structures fo…

The $F / D$ ratio and meson-baryon couplings from QCD sum rules-II

Hungchong Kim, Takumi Doi, Makoto Oka +1

Using QCD sum rules, we compute the diagonal meson-baryon couplings, $π N N$ , $η N N$ , $π ΞΞ$ , $η ΞΞ$ , $π ΣΣ$ and $η ΣΣ$ , from the baryon-baryon correlation function with a meson, $i\int d…

QCD sum rules for J/psi in the nuclear medium: calculation of the Wilson coefficients of gluon operators up to dimension 6

Sungsik Kim, Su Houng Lee

We calculate the Wilson coefficients of all dimension 6 gluon operators with non zero spin in the correlation function between two heavy vector currents. For the twist-4 part, we f…
