Abstract We study two- and three-baryon systems with two units of charm looking for possible bound states or resonances. All two-baryon interactions are consistently derived from a constituent quark model tuned in the light-flavor hadron phenomenolog

Abstract We present a comparative study of the charmed baryon–nucleon interaction based on different theoretical approaches. For this purpose, we make use of (i) a constituent quark model tuned in the light-flavor baryon–baryon interaction and th

Recent Λ3H lifetime measurements in relativistic heavy ion collision experiments have yielded values shorter by (30±8)% than the free Λ lifetime τΛ, thereby questioning the naive expectation τ(HΛ3)≈τΛ for a weakly bound Λ hyperon. Here we

By solving exactly the Faddeev equations for the bound-state problem of three mesons, we demonstrate that current theoretical predictions pointing to the existence of a deeply-bound doubly bottom axial vector tetraquark lead to the existence of a uni

Abstract We study the width of a two-body resonance in a coupled-channel system. We demonstrate how the width does not come only determined by the available phase space for its decay to the detection channel, but it greatly depends on the relative po

It has been recently reported an intriguing theoretical result of a narrow three-body resonance with a large available phase space [1]. The resonance was reported in the NΛΛ−ΞNN system near the Ξd threshold, having a very small width in spite o

Relativistic effects in a three-body calculation of the $np\to\eta d$ process are considered. Relativistic effects on the range and strength of the pion exchange contribution to the reaction mechanism may be large, but boost effects of the two-body i

We have recently studied hidden-charm pentaquarks, $c\bar c qqq$, using dynamical correlations between the heavy quarks arising from the Coulomb-like nature of the short-range interaction. A pattern was obtained that compares well with the experiment
