Sign convention of residues in QCD sum rules

Seungho Choe

We show that signs of pole residues $λ_{N}, λ_{Λ}, λ_{Σ}, λ_{Ξ}$ for $\frac{1}{2}^{+}$ octet baryons are identical in the QCD sum rule approach. To do this we compare signs of meson-baryon cou…

Vector mesons in medium with finite three momentum

Su Houng Lee

We formulate a QCD sum rule to find the three momentum dependence of the peak position of the vector meson spectral density in nuclear medium. We find less than 2 % (0.1 %) shift o…

Calculation of $g_{π N S_{11}}$ and $g_{η N S_{11}}$ Couplings in QCD Sum Rules

Hungchong Kim, Su Houng Lee

We calculate the coupling constants, $g_{π N S_{11}}$ and $g_{ηNS_{11}}, using QCD sum rules in the presence of an external meson field. A covariant derivative is introduced within t…

Comment on ``Meson Masses in Nuclear Matter''

T. Hatsuda, Su H. Lee

In a recent paper, Eletsky and Ioffe estimated the energy shift of $ρ$ -meson with high momentum (q) in nuclei using the Glauber approximation. They also made remarks on the low q v…
