Non-diagonal DVCS with spinless hadron-to-two-hadron transition $γ^* Ï\to γÏÏ$
Sangyeong Son
We present the formalism of hadron-to-two-hadron transition generalized parton distributions (GPDs) for spinless hadron case. Definitions of the twist-2 unpolarized and polarized $…

Non-diagonal DVCS and transition GPDs: A unified framework for spinless hadron case $γ^* Ï\to γÏÏ$
Sangyeong Son, Kirill M. Semenov-Tian-Shansky
Hadron-to-two-hadron transition generalized parton distributions (GPDs) extend the concept of hadron-to-resonance transition GPDs and provide a unified description of non-diagonal…

Effective Lagrangian for strong and electromagnetic interactions of high-spin resonances
Sang-Ho Kim, Yongseok Oh, Sangyeong Son +2
Recent experiments of photon-nucleon and meson-nucleon scatterings have accumulated a lot of data for various meson production processes. One of the purposes of those experiments i…
