Baryon masses from QCD current correlators at T ≠ 0

Correlation functions of QCD currents with quantum numbers of nucleon and Δ-isobar are considered at finite temperatures. Corrections of order T 4 to the correlators are calculated and interpreted in terms of thermal mass shifts using a QCD sum rules type of argument. In both cases the masses decrea...

Description
Summary:Correlation functions of QCD currents with quantum numbers of nucleon and Δ-isobar are considered at finite temperatures. Corrections of order T 4 to the correlators are calculated and interpreted in terms of thermal mass shifts using a QCD sum rules type of argument. In both cases the masses decrease with T.
