The doubly virtual $(π^{0}, η, η^{'}) \to γ^{} γ^{}$ transition form factors in the light-front quark model

Ho-Meoyng Choi, Hui-Young Ryu, Chueng-Ryong Ji

We report our investigation on the doubly virtual TFFs $F_{P γ^{*}} (Q_{1}^{2}, Q_{2}^{2})$ for the $P \to γ^{*} (q_{1}) γ^{*} (q_{2}) (P = π^{0}, η, η^{'})$ transitions using the light-front qua…

Diffractive Vector Photoproduction using Holographic QCD

Chang Hwan Lee, Hui-Young Ryu, Ismail Zahed

We discuss diffractive photon-production of vector mesons in holographic QCD. At large $s$ , the QCD scattering amplitudes are reduced to the scattering of pair of dipoles ex…

Systematic twist expansion of $(η_{c}, η_{b}) \to γ^{*} γ$ transition form factors in light-front quark model

Hui-Young Ryu, Ho-Meoyng Choi, Chueng-Ryong Ji

The light-front quark model analysis of the meson-photon transition form factor $F_{P γ} (Q^{2})$ amenable both for the spacelike region ( $Q^{2} > 0$ ) and the timelike region ( $Q^{2} < 0$ )…

Spacelike and timelike form factors for the $(π^{0}, η, η^{'}) \to γ^{*} γ$ transitions in the light-front quark model

Ho-Meoyng Choi, Hui-Young Ryu, Chueng-Ryong Ji

We investigate the $(π^{0}, η, η^{'}) \to γ^{*} γ$ transitions both for the spacelike region and the timelike region using the light-front quark model (LFQM). In particular, we present the new…

Gluonic magnetic susceptibilities of the QCD vacuum

Hui-Young Ryu, Seung-il Nam, Hyun-Chul Kim

This paper has been withdrawn by the authors due to a serious technical error in treating the quark form factors F in the gluon operators.
