The quark model was formulated in 1964 to classify mesons as bound states made of a
quark–antiquark pair, and baryons as bound states made of three quarks. For a long time all …

Since the discovery of the first charmed meson in 1976, many open-charm and open-bottom
hadrons were observed. In 2003 two narrow charm-strange states $ D_ {s0}^{\ast}(2317) …

Inspired by the newly observed P ψ s Λ (4338) and the reported P cs (4459), we indicate the
existence of the molecular-type characteristic mass spectrum for hidden-charm pentaquark …

Inspired by the recent observations of T cs¯ 0 0/++ in the processes B 0→ D¯ 0 D s+ π-and
B+→ DD s+ π+ by LHCb Collaboration, we investigate the decay properties of the T cs¯ 0 0 …

In this work we systematically calculate the mass spectra of open charm and bottom
tetraquarks qqq¯ Q¯ within an extended relativized quark model. The four-body relativized …

We have systematically investigated the mass spectrum and rearrangement decay
properties of the exotic tetraquark states with four different flavors using a color-magnetic …

We provide comprehensive investigations for the mass spectrum of exotic open-flavor
charmed/bottom sqq¯ c¯, qqq¯ c¯, sqq¯ b¯, qqq¯ b¯ tetraquark states with various spin …

We investigate the a 0 (980) resonance within chiral effective field theory through a three-
coupled-channel analysis, namely, π η, KK¯, and π η′. A global fit to recent lattice finite …

Stimulated by the recent observation of Ω c as well as past observations of P c (4380) and P
c (4450), we perform a coupled-channel analysis of Ξ c* K¯/Ω c η/Ω c* η/Ξ c K¯*/Ξ c′ K¯*/Ω …

The D0 collaboration has recently reported a narrow peak structure in the B s 0 π±invariant-
mass spectrum, which is called X (5568). Its proposed quantum numbers JP= 0+/1+ are not …
