Conformal Symmetry and Pion Form Factor: Space- and Time-like Region

Ho-Meoyng Choi, Chueng-Ryong Ji

We extend a recent analysis of the pion electromagnetic form factor constrained by the conformal symmetry to explore the time-like region. We show explicitly that the time-like for…

Space- and time-like form factors for $ω \to π γ^{}$ and $K^{} \to K γ^{*}$ in light-front quark model

Ho-Meoyng Choi

We investigate space- and time-like form factors for $ω \to π γ^{*}$ and $K^{*} \to K γ^{*}$ decays using the light-front quark model constrained by the variational principle for the QCD-moti…

Perturbative QCD analysis of exclusive J/ψ+η_c production in e^+e^- annihilation

Ho-Meoyng Choi, Chueng-Ryong Ji

We analyze the exclusive charmonium $J / ψ + η_{c}$ pair production in $e^{+} e^{-}$ annihilation using the nonfactorized perturbative QCD and the light-front quark model(LFQM) that goes beyo…

Distribution amplitudes and decay constants for $(π, K, ρ, K^{*})$ mesons in light-front quark model

Ho-Meoyng Choi, Chueng-Ryong Ji

We present a calculation of the quark distribution amplitudes(DAs), the Gegenbauer moments, and decay constants for $π, ρ, K$ and $K^{*}$ mesons using the light-front quark model. Whil…

Decay constants and radiative decays of heavy mesons in light-front quark model

Ho-Meoyng Choi

We investigate the magnetic dipole decays $V \to P γ$ of various heavy-flavored mesons such as $(D, D^{*}, D_{s}, D_{s}^{*}, η_{c}, J / ψ)$ and $(B, B^{*}, B_{s}, B_{s}^{*}, η_{b}, Υ)$ using the light-front quar…

New Progress in Time-Like Exclusive Processes

Chueng-Ryong Ji, Ho-Meoyng Choi

We discuss a necessary nonvalence contribution in timelike exclusive processes. Following a Schwinger-Dyson type of approach, we relate the nonvalence contribution to an ordinary l…
