چکیده انگلیسی
I study the Ds(2317) and Ds(2457) discovered at BaBar, CLEO and Belle, and find that they belong to a class of strange S=â1 tetraquarks and pentaquarks, which is equivalent to the class of kaonic molecules bound by short range attraction. In this class of hadrons a kaon is strongly trapped by a s-wave meson or baryon. To describe this class of multiquarks the Resonating Group Method is applied to a standard quark model with chiral symmetry breaking, and the short range kaon-meson(baryon) interactions are extracted. A criterion is derived to classify the attractive channels. I conclude that the mesons Bs(0+),Bs(1+), and the baryons Ωcc,Ωcb,Ωbb clearly belong to the new hadronic class of the Ds(2317) and Ds(2457). The hadrons f0(980),Î,Σc,Σb possibly belong to a related family.
