Mesons and nucleons from holographic QCD in a unified approach
Hyun-Chul Kim, Youngman Kim, Ulugbek Yakhshiev
We investigate masses and coupling constants of mesons and nucleons within a hard wall model of holographic QCD in a unified approach. We first examine an appropriate form of fermi…
Photoproduction of Theta^+(1540,1/2^+) reexamined with new theoretical information
Seung-il Nam, Hyun-Chul Kim
We reinvestigate the photoproduction of the exotic pentaquark baryon Theta^+(1540,1/2^+) from the gamma N -> Kbar Theta^+ reaction process within the effective Lagrangian approach,…
Quark-gluon mixed condensate of the QCD vacuum in Holographic QCD
Hyun-Chul Kim, Youngman Kim
We investigate the quark-gluon mixed condensate based on an AdS/QCD model. Introducing a holographic field dual to the operator for the quark-gluon mixed condensate, we obtain the…
Axial-vector transitions and strong decays of the baryon antidecuplet in the self-consistent SU(3) chiral quark-soliton model
Tim Ledwig, Hyun-Chul Kim, Klaus Goeke
We investigate the axial-vector transition constants of the baryon antidecuplet to the octet and decuplet within the framework of the self-consistent SU(3) chiral quark-soliton mod…
Pion weak decay constant at finite density from the instanton vacuum
Seung-il Nam, Hyun-Chul Kim
We investigate the pion weak decay constant (F_pi) and pion mass (m_pi) at finite density within the framework of the nonlocal chiral quark model from the instanton vacuum with the…
Vector transition form factors of the and in the SU(3) chiral quark-soliton model
Tim Ledwig, Hyun-Chul Kim, Klaus Goeke
We investigate the vector transition form factors of the nucleon and vector meson K^* to the pentaquark baryon Theta^+ within the framework of the SU(3) chiral quark-soliton model.…
