Hadronic screening masses and the magnetic gluon condensate at high temperature

Abstract

The hadronic screening mass at high temperature ($T$) in QCD${}_4$ is examined on the basis of the QCD sum rules in (2+1) dimensions. Due to the magnetic gluon condensate at high $T$ which is expected to be nonvanishing, the screening mass deviates from the asymptotic value $2\pi T$. Also, the screening mass in the vector (pseudo-vector) channel turns out to be heavier than that in the scalar (pseudo-scalar) channel.
