Book excerpt: Radiative decays of the radically excited charmonium resonance, [psi](2S), into[pi][pi], K[bar K] and[eta][eta] final states have been measured in a sample of 3.96 x 10[sup 6][psi](2S) events collected by the BES collaboration. The branching ratios B([psi](2S)[yields][gamma]f[sub 2](1270))= (2.27[+-] 0.26[+-] 0.39) x 10[sup -4] and B([psi](2S)[yields][gamma]f[sub 0](1710)) x B(f[sub 0](1710)[yields] K[sup+]K[sup -])= (5.59[+-] 1.12[+-] 0.93) x 10[sup -5] are obtained. When compared to the corresponding radiative J/[psi] decays, the observed[psi](2S) radiative decay rates into[gamma]f[sub 2](1270) and[gamma]f[sub 0](1710) are consistent with the ''15%'' rule.

Available in PDF, EPUB and Kindle. Book excerpt: The results of amplitude analyses of the Mark III data on the K[sub s][sup 0]K[sub s][sup 0], K[sup+]K[sup -] and[pi][sup+][pi][sup -] systems produced in J/[psi] radiative decay are shown for the mass range 1--2 GeV. The intensity distributions for the amplitudes having J[sup PC] values 0[sup+2] and 2[sup+2] are presented and discussed. The observed strong production of the f[sub 0](1700) in J/[psi] radiative decay suggests that this state may consist primarily of the lightest scalar glueball state. No significant production of spin 2 is observed in the 1.7 GeV mass region.

Book excerpt: Inclusive and exclusive measurements of psi radiative decay are presented. The magnitude of hard inclusive radiative decay is comparable to the prediction f first order QCD, but the measured spectrum is considerably softer. In addition to measurements of radiative decays to the known pseudoscalar and tensor mesons, a sizable decay to a resonance of mass 144015/sup +10/ MeV/c2 in the K anti K.pi. mode is observed. This may be the E(1420) meson. Supporting evidence is presented for the existence of the n/sub c/ at a mass of 2980 MeV/c2.
