Dipole and Quadrupole Moments of Mirror Nuclei 8B and 8li

G. Kim, R. R. Khaydarov, Il-Tong Cheon +1

Magnetic dipole and electric quadrupole moments of the mirror nuclei 8Li and 8B are analysed in the framework of the multiparticle shell model by using two approaches : i) the one-…

An Isobaric Model for Kaon photoproduction

Bong Soo Han, Myung Ki Cheoun, K. S. Kim +1

The kaon photoproduction is analyzed up to =2.0 GeV by using an isobaric model based on effective Lagrangians and by taking a cross symmetry into account. Both {\it…

Pion and Kaon Electromagnetic Form Factors in a Effective Lagrangian

Yun Chang Shin, Bong Soo Han, Myung Ki Cheoun +2

A SU(2) effective lagrangian is extended to a by including the vector and axial vector meson. With this effective lagrangian, electromagnetic form fact…

Meson-baryon couplings and the ratio from QCD sum rules

Hungchong Kim, Takumi Doi, Makoto Oka +2

Motivated by the recent work on the calculation of the coupling constant using QCD sum rule beyond the chiral limit, we construct the corresponding sum rules for the coupling…

The charge radii and the decay rates of the pseudoscalar meson

Yongkyu Ko

The charge radii and the decay rates of the pion and kaons are calculated, using the relativistic equation of motion with a linear potential. Those physical quantities are quite we…

Coulomb Distortion Effects for (e,e'p) Reactions at High Electron Energy

K. S. Kim, L. E. Wright

We report a significant improvement of an approximate method of including electron Coulomb distortion in electron induced reactions at momentum transfers greater than the inverse o…

Vector mesons in dense matter

Su Houng Lee

We will summarize the progress in understanding the changes in the vector meson spectral density in nuclear medium using the constraint equations obtained from the Borel transforme…

Importance of the Doppler Effect to the Determination of the Deuteron Binding Energy

Yongkyu Ko, Myung Ki Cheoun, Il-Tong Cheon

The deuteron binding energy extracted from the reaction is reviewed with the exact relativistic formula, where the initial kinetic energy and the Doppler effect a…

Constraints on vector mesons with finite momentum in nuclear matter

Bengt Friman, Su Houng Lee, Hungchong Kim

Using the QCD operator product expansion, we derive the real part of the transverse and longitudinal vector-vector correlation function with the quantum numbers of the rho and omeg…

QCD sum rules with two-point correlation function

Hungchong Kim, Su Houng Lee, Makoto Oka

We construct three different sum rules from the two-point correlation function with pion, , beyond the soft-pion limit. T…
