The fully charm and bottom pentaquarks, ie, ccccc¯ and bbbbb¯, with spin-parity quantum
numbers JP= 1 2-, 3 2-, and 5 2-, are investigated within a lattice-QCD inspired quark model …

We review how lattice QCD can contribute to the prediction and the comprehension of
tetraquarks, pentaquarks and related exotic hadrons such as hybrids, with at least one …

The lowest-lying charmonium-like tetraquarks\(c {\bar {c}} q {\bar {q}}\)\((q= u,\, d)\) and\(c
{\bar {c}} s {\bar {s}}\), with spin-parity\(J^ P= 0^+\),\(1^+\) and\(2^+\), and isospin\(I= 0\) and …

In the framework of the chiral quark model along with complex scaling range, we perform a
dynamical study on the low-lying S-wave double-heavy tetraquark states (QQ q¯ q¯, Q= c, b …

The hadroquarkonium picture [S. Dubynskiy and MB Voloshin, Phys. Lett. B 666, 344 (2008)
PYLBAJ 0370-2693 10.1016/j. physletb. 2008.07. 086] provides one possible interpretation …

With the development of high energy physics experiments, a large amount of exotic states in
the hadronic sector have been observed. In order to shed some light on the nature of the …

The past seventeen years have witnessed tremendous progress on the experimental and
theoretical explorations of the multiquark states. The hidden-charm and hidden-bottom …

Fully-heavy tetraquark states, ie, ccc¯ c¯, bbb¯ b¯, bbc¯ c¯(ccb¯ b¯), cbc¯ c¯, cbb¯ b¯, and
cbc¯ b¯, are systematically investigated by means of a nonrelativistic quark model based on …

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 …

According to the classification of the quark model, the hadrons going beyond three-quark
baryon and quark-antiquark meson pictures are called exotic hadrons. Many new hadrons …
