The past decades witnessed the golden era of hadron physics. Many excited open heavy
flavor mesons and baryons have been observed since 2017. We shall provide an updated …

Chiral symmetry and its spontaneous breaking play an important role both in the light
hadron and heavy hadron systems. The chiral perturbation theory (χ PT) is the low energy …

Inspired by the observation of the P ψ s Λ (4459) and P ψ s Λ (4338), we systematically
investigate the magnetic moments, the transition magnetic moments, and the radiative decay …

We have a look at the P cs states generated from the interaction of D¯(⁎) Ξ c (′⁎) coupled
channels. We consider the blocks of pseudoscalar-baryon (1 2+, 3 2+) and vector-baryon (1 …

The discoveries of the P ψ s Λ (4459) and P ψ s Λ (4338) as the potential Ξ c D¯(*)
molecules have sparked our curiosity in exploring a novel class of molecular P ψ s Λ/Σ …

Recently, the LHCb Collaboration has reported two strange hidden-charm pentaquark states
named P ψ s Λ (4459) and P ψ s Λ (4338) in the J/ψ Λ invariant mass spectra of decays Ξ b …

Motivated by the observed P ψ s Λ (4459)/P ψ s Λ (4338) and T cc (3875)+ states as the Ξ c
D¯*/Ξ c D¯ and DD* molecular candidates, respectively, in this work we investigate the Ξ c …

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 …

The recently observed strange pentaquark candidate, P ψ s Λ (4338) 0, is investigated to
provide information about its nature and substructure. To this end, its mass and width …

We investigate the mass spectrum of the molecular pentaquarks composed of a baryon and
a meson. We establish the underlying relations among the near-threshold interactions of the …
