Proposes that a K* Ξ molecular state (Λ(2150)) generates a triangle singularity explaining the peak in K- p → K Ξ(1530), with distinct spin density matrix element variations as a testable signature.
Neural-network quantum states are used to compute spectra of fully-heavy multiquarks in a non-relativistic quark model, claiming to overcome dimensionality issues with superior accuracy over prior approximations.
Coupled-channel calculations show Pc and Pcs states as molecular bound states with RMS radii 0.5-2 fm when heavy-quark spin symmetry is respected across all channels.
An overview of the contact interaction model shows it describes the mass spectrum and form factors of forty mesons and their diquark partners with comparisons to lattice QCD and other approaches.
The NJL model is shown to produce parton distribution functions and electromagnetic form factors consistent with data by imitating QCD chiral symmetry breaking and confinement.
