A Theory of Scalar Mesons
G. 't Hooft, G. Isidori, L. Maiani +2
We discuss the effect of the instanton induced, six-fermion effective Lagrangian on the decays of the lightest scalar mesons in the diquark--antidiquark picture. This addition allo…
Indications of a Four-Quark Structure for the X(3872) and X(3876) Particles from Recent Belle and BABAR Data
L. Maiani, A. D. Polosa, V. Riquer
Recent results by BELLE and BaBar point to the existence of a second X particle decaying in D^0 D^0bar pi^0, a few MeV above the X(3872). We identify the two X states with the neut…
Structure of Light Scalar Mesons from D_s and D^0 Non-Leptonic Decays
L. Maiani, A. D. Polosa, V. Riquer
Non-leptonic D meson decays may provide a reliable testbed for the multiquark interpretation of light scalar mesons. In this letter we consider D_s decay and show that a 4-quark f_…
Counting valence quarks at RHIC and LHC
L. Maiani, A. D. Polosa, V. Riquer +1
We consider the Nuclear Modification Ratios in heavy ion collisions, R_CP and R_AA, in the region of intermediate transverse momentum, and study the dependency upon the constituent…
Positive Parity Scalar Mesons in the 1-2 GeV Mass Range
L. Maiani, F. Piccinini, A. D. Polosa +1
Based on the observation that K_0(1430) is lighter than its SU_3 counterpart, a_0(1450), we examine the possibility that these particles, together with f_0(1370), f_0(1500) and f_0…
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…
