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.

We study the Ξ b (6100) using the methods of QCD sum rules and light-cone sum rules within the framework of heavy quark effective theory. Our results suggest that the Ξ b (6100) can be well interpreted as the P -wave bottom baryon of J P = 3/2 − , belonging to the SU (3) flavor 3F representation. It has a partner state of J P = 1/2 − , labelled as Ξ b (1/2 − ), whose mass and width are predicted to be m Ξ b (1/2 − ) = 6.08 +0.13 −0.11 GeV and Γ Ξ b (1/2 − ) = 4 +29 − 4 MeV, with the mass splitting ∆M = m Ξ b (6100) − m Ξ b (1/2 − ) = 9 ± 3 MeV. We propose to search for it in the Ξc(1/2 − ) → Ξ b π decay channel. Our results also suggest that the Λ b (5912) and Λ b (5920) are their partner states with J P = 1/2 − and 3/2 − respectively, and moreover, the Λc(2595), Λc(2625), Ξc(2790), and Ξc(2815) are their charmed partner states.
