Final-state interaction and screening have a great influence on qq̄ production cross sections, which are important quantities in many problems in quark-gluon plasma physics. They lead to an enhancement of the cross section for a qq̄ color-singlet state and a suppression for a color-octet state. The effects are large near the production threshold. The presence of screening gives rise to resonances...

We apply the Low's theorem to soft gluon emission from heavy quark scattering in nonperturbative strongly interacting quark-gluon plasma (sQGP). The sQGP is described terms of dynamical quasi-particles and adjusted reproduce EoS lQCD at finite temperature chemical potential. Since emitted long wavelength, it does not provide information on detailed structure scattering, only incoming outgoing p...
