Abstract
Final-state interaction and screening have a great influence on\(q\bar q\) 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\(q\bar q\) 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 for\(q\bar q\) production just above the threshold at specific plasma temperatures. These resonances, especially\(c\bar c\) and\(b\bar b\) resonances, may be utilized to search for the quark-gluon plasma by studying the temperature dependence of heavy-quark pair production just above the threshold.
