Review of the QCD sum rules for exotic states

High Energy Physics - Phenomenology 2025-09-09 v6

Abstract

We review the exotic states, such as the XX, YY, ZZ, TT and PP states, and present their possible assignments based on the QCD sum rules. We present many predictions which can be confronted to the experimental data in the future to diagnose the exotic states. Furthermore, we also mention other theoretical methods.
