Is the X(3872) Production Cross Section at Tevatron Compatible with a Hadron Molecule Interpretation?
C Bignamini, B Grinstein, F Piccinini +2
The X(3872) is universally accepted to be an exotic hadron. In this letter we assume that the X(3872) is a D0 \bar D0* molecule, as claimed by many authors, and attempt an estimate…
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…
J/psi Absorption in Heavy Ion Collisions II
L. Maiani, F. Piccinini, A. D. Polosa +1
Using the methods introduced in a previous paper, we consider the dissociation of J/psi by the lowest-lying pseudoscalar and vector mesons in the hadronic fireball formed in heavy…
A new look at scalar mesons
L. Maiani, A. Polosa, F. Piccinini +1
Light scalar mesons are found to fit rather well a diquark-antidiquark description. The resulting nonet obeys mass formulae which respect, to a good extent, the OZI rule. OZI allow…
