Lots of charmonium-like structures have been observed in the last two decades. Most of
them have quantum numbers that can be formed by a pair of charm and anticharm quarks …

The search for mesons with non-quark-antiquark (exotic) quantum numbers has gone on for
nearly 30 years. Currently there is experimental evidence of three isospin one states, the π 1 …

The primary objective of this study is to investigate hadronic molecules of K⁎ K¯ 1 (1270)
using a one-boson-exchange model, which incorporates exchanges of vector and …

We calculated next-to-leading-order (NLO) QCD perturbative contributions to a JPC= 0+-,
dud¯ u¯ tetraquark (diquark-antidiquark) correlator in the chiral limit of massless u and d …

The quark potential model for mesons and its extension for hybrid mesons are used to study
the effects of radial excitations on the masses, sizes, and radial wave functions at the origin …

We study the exotic JPC= 0--four-quark states in Laplace sum rules and finite energy sum
rules. We use the vector tetraquarklike currents as interpolating currents in the correlator …

In this work, we propose that the odderon is a Regge spin-3 odd-glueball tensor. To
demonstrate the proposal, we study the pp and pp¯ elastic scattering by including the …

In this work, the spectra of the prospective exotic hidden-charm and hidden-bottom
baryonium, viz. the baryon–antibaryon states, with J PC= 0--and 0+-are investigated in the …

Highlights in the search for nonconventional (non-qq¯) meson states are the π1 (1400) and
π1 (1600) exotic candidates. Should they exist, mounting theoretical arguments suggest that …
