In-Medium Modification of Meson Mass over Temperature and Momentum
Hidefumi Matsuda, Philipp Gubler, Koichi Hattori
We analyze the in-medium modification of the meson mass below the pseudo-critical temperature at vanishing baryon chemical potential using QCD sum rules. The sum r…

Polarization dependence of the meson from finite-temperature QCD sum rules
Hidefumi Matsuda, Philipp Gubler, Koichi Hattori
We study the meson at finite temperature and finite momentum using QCD sum rules. The presence of medium breaks the Lorentz invariance, and induces distinct in-medium modificat…
