Light Vector Mesons in Nuclear Matter

T. Hatsuda, H. Shiomi, H. Kuwabara

We summarize the current theoretical and experimental status of the spectral changes of vector mesons ( $ρ$ , $ω$ , $ϕ$ ) in nuclear medium. Various approaches including QCD sum rules,…

Second Class Current in QCD Sum Rules

H. Shiomi

Induced tensor charge of the nucleon $g_{T}$ , which originates from G-parity violation, is evaluated from QCD sum rules. We find that $g_{T} / g_{A}$ with $g_{A}$ being the axial charge is $…

QCD Sum Rules, Scattering Length and the Vector Mesons in Nuclear Medium

Tetsuo Hatsuda, Su Houng Lee, Hiroyuki Shiomi

Critical examination is made on the relation between the mass shift of vector mesons in nuclear medium and the vector-meson $-$ nucleon scattering length. We give detailed comparis…

The Pion-Nucleon Coupling Constant in QCD Sum Rules

H. Shiomi, T. Hatsuda

The pion-nucleon coupling constant $g_{π N}$ is studied on the basis of the QCD sum rules. Both the Borel sum rules and the finite energy sum rules for $g_{π N}$ are used to examine…

We summarize the current theoretical and experimental status of the spectral change of the vector mesons in dense matter.

Vector Mesons in Nuclear Medium -- an Effective Lagrangian Approach --

H. Shiomi, T. Hatsuda

Effective masses of $ρ$ and $ω$ mesons in nuclear medium are studied in a hadronic effective theory. Both the pole position and the screening mass decrease in nuclear matter due to…
