Book Description
Measurements of the two body decays of the J/[psi] into vector and pseudoscalar meson pairs are presented. Using the measured branching ratios, a phenomenological model of J//psi/ decays indicates that the [eta] and [eta]' are composed only of light and strange quarks, without a gluonium contribution in the [eta]' wavefunction. A measurement of J//psi/ .-->. .gamma pi./sup +/.pi./sup -/.pi./sup +/.pi./sup -/ is presented. The f1 (1285) is observed and its spin and parity are investigated. The /eta//sub c/ is observed to decay to /rho/°/rho/°, and first indications of /eta//sub c/ decays to f2f2 are presented. The spin and parity of the /eta//sub c/ are investigated. 5 figs., 3 figs., 1 tab.

Book Description
Production of prompt J/[psi] meson pairs in proton-proton collisions at √s = 7 TeV is measured with the CMS experiment at the LHC in a data sample corresponding to an integrated luminosity of about 4.7 fb-1. The two J/[psi] mesons are fully reconstructed via their decays into [mu] + [mu] - pairs. This observation provides for the first time access to the high-transverse-momentum region of J/[psi] pair production where model predictions are not yet established. The total and differential cross sections are measured in a phase space defined by the individual J/[psi] transverse momentum (p T J/[psi] ) and rapidity (

Book Description
From a data sample of 5.8 x 106 J/psi's collected by the MARK III detector at the storage ring SPEAR at SLAC, two-body decay modes of the J/psi into a vector and a tensor meson have been measured. From the studies of the tensor meson, recoiling against the ideally mixed and well understood vector mesons, quark correlations are established and compared with the theoretical expectations of the J/psi decays and the SU(3) predictions. The beginnings of a similar systematic study of the two-body vector scalar decays are also presented.
