Correlating Strangeness Enhancement and J/psi Suppression in Heavy Ion Collisions at sqrt(s)_NN = 17.2 GeV
F. Becattini, L. Maiani, F. Piccinini +2
It is shown that the strangeness enhancement and the J/psi anomalous suppression patterns observed in heavy ion collisions at top SPS energy, sqrt(s)_NN = 17.2 GeV, exhibit an inte…

Four Quark Interpretation of Y(4260)
L. Maiani, F. Piccinini, A. D. Polosa +1
We propose that the Y(4260) particle recently announced by BaBar is the first orbital excitation of a diquark-antidiquark state ([cs][cbar sbar]). Using parameters recently determi…
