J/psi and eta_c in the nuclear medium: QCD sum rule approach

Frank Klingl, Sungsik Kim, Su Houng Lee +2

We investigate the masses of the lowest c\bar{c} states, the J/psi and eta_c, in nuclear matter using QCD sum rules. Up to dimension four, the differences between the operator prod…

Radiative Muon Capture and Induced Pseudoscalar Coupling Constant in Nuclear Matter

Myung Ki Cheoun, K. S. Kim, B. S. Han +1

The recent TRIUMF experiment for $μ^{-} p \to n ν_{μ} γ$ gave a surprising result that the induced pseudoscalar coupling constant $g_{P}$ was larger than the value obtained from $μ^- p \…

The Axial Current in Electromagnetic Interaction

Myung Ki Cheoun, K. S. Kim, Il-Tong Cheon

We discussed the possibility that the charged axial currents of matter fields could be non-conserved in electromagnetic interaction at $O (e)$ order. It means that chiral symmetry…

QCD sum rule calculation of the $π N N$ coupling-revisited

Hungchong Kim, Su Houng Lee, Makoto Oka

In the conventional QCD sum rule calculation for the $π N N$ coupling beyond the soft-pion limit, there are three distinct Dirac structures, each of which can be used to construct se…

Overbarrier Resonances as Solutions of Set Inhomogeneous Schrödinger Equations

Il-Tong Cheon, G. Kim, A. V. Khugaev

In the paper the Schrödinger equation for quasibound resonance state with complex energy is considered. The system of inhomogeneous differential equations is obtained for the real…
