Spectrum and decay properties of diquonia

Using the interquark potential due to Bhaduri et al., the properties of q2q_2 systems are studied within a non-relativistic quark model. A systematics over the various flavors u, d, s, c, b, over the total spin S and over the orbital angular momentum L = 0, 1, 2, 3 is carried out, while the parity is taken as the natural one. Not only the spectrum, but also the decay properties of each state are evaluated and the wave functions are analyzed in term of dumbbell structure. We propose a number of new resonances which could have a very narrow width.
