Screening masses of scalar and pseudo-scalar excitations in quark–gluon plasma

The Quark–Gluon Plasma (QGP) excitations, corresponding to the scalar and pseudo-scalar meson quantum numbers, for different temperatures are calculated. Analysis is performed in the Hard Thermal Loop (HTL) Approximation and leads to a better understanding of the excitations of QGP in the deconfined phase and is also of relevance for lattice studies.
