An updated review of the new hadron states

Abstract

The past decades witnessed the golden era of hadron physics. Many excited open heavy flavor mesons and baryons have been observed since 2017. We shall provide an updated review of the recent experimental and theoretical progresses in this active field. Besides the conventional heavy hadrons, we shall also review the recently observed open heavy flavor tetraquark states $X(2900)$ and $T_{cc}^{+}(3875)$ as well as the hidden heavy flavor multiquark states $X(6900)$, $P_{cs}(4459{)}^0$, $Z_{cs}(3985{)}^{-}$, $Z_{cs}(4000{)}^{+}$, and $Z_{cs}(4220{)}^{+}$. We will also cover the recent progresses on the glueballs and light hybrid mesons, which are the direct manifestations of the non-Abelian $SU(3)$ gauge interaction of the Quantum Chromodynamics in the low-energy region.
