We study the decay of Θ + in a non-relativistic quark model. The wave function of Θ + is constructed for the two cases J P = 1/2 ± as products of color, spin, flavor and orbital parts respecting total antisymmetrization among the four quarks. We find that for the negative parity Θ + the width becomes very large which is of order of several hundreds MeV, while it is about a several tens MeV for ...

In this paper we show that on a general hypersurface of degree r = 3, 4, 5, 6 in P 5 a rank 2 vector bundle E splits if and only if h 1 E(n) = h 2 E(n) = 0 for all n ∈ Z. Similar results for r = 1, 2 were obtained in [15], [16] and [1].

We study the spectra of mesons and baryons, composed of light quarks, in the framework of a semirelativistic potential model including instanton induced forces. We show how a simple modification of the instanton interaction in the baryon sector allows a good description of the meson and the baryon spectra using an interaction characterized by a unique set of parameters. PACS numbers: 12.39.Pn, ...

We review the spectroscopy and some properties of hadrons containing two charmed quarks, or more generally, two heavy quarks. This includes heavy baryons such as (bcu), and possible exotic multiquark states.
