Inspired by the recent observation of new Ω c 0 states by the LHCb Collaboration, we
explore the excited Ω c states from the pentaquark perspective in the quark delocalization …

Inspired by the observation of hidden-charm pentaquark P c and P cs states by the LHCb
Collaboration, we explore the qqcc¯ c (q= u or d) pentaquark systems in the quark …

We study the near-threshold ϒ (1 S) meson photoproduction from protons and nuclei by
considering incoherent direct non-resonant (γ p→ ϒ (1 S) p, γ n→ ϒ (1 S) n) and two-step …

Multiquark systems appear less frequently than mesons and baryons despite the enormous
worldwide experimental effort that has been made during the last two decades. In this work …

The ϒ (10753) state has been recently observed by the Belle and Belle II collaborations with
enough global significance to motivate an assessment of the high-energy spectrum usually …

We investigate the P-wave states T bb-in the isospin singlet and three excited modes
[excitation occurring in the diquark [bb] c 1 s 1 (ρ-mode), antidiquark [u¯ d¯] c 2 s 2 (r-mode) …

We systematically study hidden charm pentaquark states in the constituent quark model with
a general Hamiltonian for multiquark systems, considering the coupling between the Σ c (*) …

We study the production of X (3872) mesons in photon-induced nuclear reactions near the
threshold within the collision model based on the nuclear spectral function. The model …

Motivated by the intriguing discovery of X (6900) by the LHCb collaboration, we undertake a
comprehensive study of the ss¯ ss¯ tetraquark system with positive parity, employing the …

We have investigated the $ qss\bar {q} q $($ q= u $ or $ d $) system to find possible
pentaquark explanations for the $\Xi $ resonances. The bound state calculation is carried …
