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 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 present the results of a lattice calculation of tetraquark states with quark contents q 1 q 2
Q¯ Q¯, q 1, q 2⊂ u, d, s, c and Q≡ b, c in both spin-0 (J= 0) and spin-1 (J= 1) sectors. This …

Claims concerning the possible discovery of the Θ+ pentaquark, with minimal quark content
uudds¯, have motivated our comprehensive study into possible pentaquark states using …

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

The possible discovery of the Θ+ pentaquark has motivated a number of studies of its nature
using lattice QCD. While all the analyses thus far have focused on spin-1 2 states, here we …

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 …

We continue our study of heavy-light four-quark states and find evidence from lattice QCD for
the existence of a strong-interaction-stable I (JP)= 0 (1+) udc¯ b¯ tetraquark with mass in the …

We study spin 1 2 hadronic states in quenched lattice QCD to search for a possible S=+ 1
pentaquark resonance. Simulations are carried out on 8 3× 24, 10 3× 24, 12 3× 24, and 16 …

The observed mass pattern of scalar resonances below 1 GeV suggests a tetraquark
assignment over the conventional q¯ q assignment for these states. We present a search for …
