$(I, J^{P}) = (1, 1/ 2^{+})$ $Σ N N$ quasibound state

H. Garcilazo, A. Valcarce

JLab has recently found indications of the possible existence of a $Σ N N$ resonance at $(3.14 \pm 0.84) - i (2.28 \pm 1.2)$ MeV. In the past, using models that exploit symmetries be…

Hidden-flavor pentaquarks

H. Garcilazo, A. Valcarce

We have recently studied hidden-charm pentaquarks, $c c ˉ q q q$ , using dynamical correlations between the heavy quarks arising from the Coulomb-like nature of the short-range inte…

Doubly-heavy tetraquark bound states and resonances

Jean-Marc Richard, Alfredo Valcarce, Javier Vijande

We review the predictions of the quark model for the doubly-heavy tetraquarks $QQ q ˉ q ˉ$ . The possibility of resonances near the $B B^{*}$ threshold in addition to a deeply boun…

Constituent quark-model hidden-flavor pentaquarks

H. Garcilazo, A. Valcarce

We study hidden-flavor pentaquarks, $Q Q ˉ q q q$ , based on a constituent quark-model with a standard quark-quark interaction that reproduces the low-energy meson and baryon spectr…
