The pentaquark is studied in a simple model of confinement where the quarks and the antiquark are linked by flux tubes of minimal cumulated length, and the Coulomb-like interaction, the spin-dependent terms and the antisymmetrization constraints are neglected.. The ground-state is found to be stable against spontaneous dissociation into a meson and a baryon, both in the case of five equal-mass constituents and for a static quark or antiquark surrounded by four equal masses.Comment: 8 pages, 2 figures, minor corrections, references added, to appear in Phys. Rev.

“…There is now reasonable consensus that the light pentaquark does not exist, though some puzzling positive indications are still reported [15]. For a recent discussion, see, e.g., [16]. Nevertheless, the question of multiquarks remains important.…”

“…Since in the double-pionic fusion reactions to 3 He [27] and 4 He [28] the signature of this resonance is observed too, it obviously is robust enough to survive even in a nuclear surrounding, which may have interesting consequences for nuclear matter under extreme conditions.…”

Abstract.New results in the field of dibaryons are discussed concentrating on the d * (2380) resonance with I(J P ) = 0(3 + ), which has been observed first in the doublepionic fusion to deuterium and meanwhile also in neutron-proton scattering -establishing it thus as a genuine s-channel resonance. Double-pionic fusion reactions to the He isotopes demonstrate that this resonance survives also in a nuclear surrounding. It also has been shown to contribute to dilepton production helping thus to resolve the so-called DLS puzzle. Moreover, the existence of dibaryons has also an impact on the equation of state for nuclear matter.

“…Despite their long painful history [1,2] dibaryon searches (where "dibaryon" means a state with baryon number B = 2 without inference on its internal structure [hexaquark/baryonic-molecule]) have recently received new interest. This has been motivated by the recognition that there are more complex quark configurations than just the familiar q q and qqq systems.…”

Experiments at the Juelich Cooler Synchrotron (COSY) have now found compelling evidence for a new resonant state in the two-baryon system with mass 2380 MeV and a width of 70 MeV. The structure, containing six valence quarks, constitutes a so-called dibaryon, either a hexaquark or a hadronic molecule. The new particle denoted now d * (2380) has quantum numbers I(J p ) = 0(3 + ). The present knowledge about the d * dibaryon as well as other implications and possible future experiments are discussed. Experimental evidences for a dibaryon resonanceThe golden reaction channel for the observation of the d * (2380) turned out to be pn → dπ 0 π 0 , due to the absence of the isovector background (present in pn → dπ + π − ) and only moderate contributions
