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) …

In this paper, we present a review of recent works on weak decay of heavy mesons and
baryons with two mesons, or a meson and a baryon, interacting strongly in the final state …

The recently discovered T c c+ is evaluated as a DD⁎ molecular structure in the JP= 1+
sector. A coupled-channels calculation in charged basis, considering the D 0 D⁎+, D+ D⁎ 0 …

We investigate the tetraquark bound states that are manifestly exotic using three distinct few-
body methods; Gaussian expansion method (GEM), resonating group method (RGM), and …

We revisit the bottomonium spectrum motivated by the recently exciting experimental
progress in the observation of new bottomonium states, both conventional and …

We use the diffusion Monte Carlo (DMC) method to calculate the doubly heavy tetraquark T
cc system in two kinds of constituent quark models, the pure constituent quark model …

The hidden-charm tetraquarks with strangeness, cc¯ sq¯(q= u, d), in JP= 0+, 1+, and 2+ are
systematically investigated in the framework of real-and complex-scaling range of a chiral …

We review how quark models are able to describe the phenomenology of the charm meson
sector. The spectroscopy and decays of charmonium and open charm mesons are …

The constituent quark model is used to compute the ground and excited state masses of
QQQbaryons containing either c or bquarks. The quark model parameters previously used to …

Singly, doubly, and fully charmed tetraquark candidates, eg, T cs¯(2900), T cc+(3875), and
X (6900) have been recently reported by the LHCb collaboration. Therefore, it is timely to …
