From a Long-standing Prediction to a New Family of Hadrons
Abstract
Fully charmed tetraquarks have evolved from a long-standing theoretical prediction into one of the most active frontiers in hadron spectroscopy. This article reviews their development from early theoretical studies and experimental searches to the recent breakthroughs at the Large Hadron Collider, with particular emphasis on the contributions of the Nanjing Normal University (NNU) and Tsinghua University (THU) teams at the CMS experiment. We summarize the discovery of the fully charmed tetraquark family, the establishment of interference among resonances, and the first determination of their quantum numbers. These advances have transformed the search for a single exotic resonance into the study of a new family of hadrons and opened a promising avenue for exploring the nonperturbative dynamics of Quantum Chromodynamics.
