Study of Multiquarks Systems in a Chiral Quark Model
Abstract
We discuss the stability of multiquark systems within the recent model of Glozman et al. where the chromomagnetic hyperfine interaction is replaced by pseudoscalar-meson exchange contributions. In this model the (u,d) diquark S=0 I=0 is strongly bound (more than for the chromomagnetic interaction) and this leads to a bound heavy tetraquark QQ\bar q\bar q where the light quarks are in the S=0 I=0 configuration. We study the stability of other multiquark systems as well.
