夸克偶素（重夸克Q=c，B和相应的反夸克的束缚态）的有价值的数据最近由各种来源提供，主要是碰撞，但也有强子相互作用。这允许一个彻底的更新的电磁和强跃迁的夸克粒子的实验和理论状态。讨论了$Q\overline{Q}$到其他$Q\overline{Q}$态的跃迁，并参考了涉及$Q\overline{Q}$湮灭的过程。
Valuable data on quarkonia (the bound states of a heavy quark $Q=c,b$ and the corresponding antiquark) have recently been provided by a variety of sources, mainly ${e}^{+}{e}^{\ensuremath{-}}$ collisions, but also hadronic interactions. This permits a thorough updating of the experimental and theoretical status of electromagnetic and strong transitions in quarkonia. The $Q\overline{Q}$ transitions to other $Q\overline{Q}$ states are discussed, with some reference to processes involving $Q\overline{Q}$ annihilation.
