Four-Quark Hadrons: an Updated Review
Angelo Esposito, Andrea L. Guerrieri, Fulvio Piccinini +2
The past decade witnessed a remarkable proliferation of exotic charmonium-like resonances discovered at accelerators. In particular, the recently observed charged states are clearl…
Hidden-Beauty Charged Tetraquarks and Heavy Quark Spin Conservation
A. Ali, L. Maiani, A. D. Polosa +1
Assuming the dominance of the spin-spin interaction in a diquark, we point out that the mass difference in the beauty sector M(Z_b^prime) - M(Z_b) scales with quark masses as expec…
Production of Tetraquarks at the LHC
A. L. Guerrieri, F. Piccinini, A. Pilloni +1
The high prompt production cross section of X(3872) at hadron colliders has shown to be very informative about the quark nature of the X, Y, Z states. We present here a number of r…
The Z(4430) and a New Paradigm for Spin Interactions in Tetraquarks
L. Maiani, F. Piccinini, A. D. Polosa +1
Following the recent confirmation of the Z+(4430) resonance with J^{PG}=1^{++}, we have re-examined the model of S- and P-wave tetraquarks. We propose a `type-II' diquark-antidiqua…
