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: The role of scalar mesons in radiative vector meson decays is investigated. The effects of scalar-isoscalar f_{0}(980) and scalar-isovector a_{0}(980) mesons are studied in the mechanism of the radiative Phi->pi{+}pi{-}gamma and phi->pi{0}eta gamma decays, respectively. A phenomenological approach is used to study the radiative phi->pi{+}p{-}gamma decay by considering the contributions of sigma-meson, rho-meson and f_{0}-meson. The interference effects between different contributions are analyzed and the branching ratio for this decay is calculated. The radiative phi->pi{0}eta gamma decay is studied within the framework of a phenomenological approach in which the contributions of rho-meson, chiral loop and a_{0}-meson are considered. The interference effects between different contributions are examined and the coupling constants g_{phi a_{0} gamma} and g_{a_{0}K{+}K{-}} are estimated using the experimental branching ratio for the phi->pi{0}eta gamma decay. Furthermore, the radiative rho{0}pi{+}pi{-}gamma$ and rho{0}->pi{0}pi{0}gamma decays are studied to investigate the role of scalar-isoscalar sigma-meson. The branching ratios of the rho{0}->pi{+}pi{-}gamma and rho{0}->pi{0}pi{0}gamma decays are calculated using a phenomenological approach by adding to the amplitude calculated within the framework of chiral perturbation theory and vector meson dominance the amplitude of sigma-meson intermediate state. In all the decays studied the scalar meson intermediate states make important contributions to the overall amplitude.

Book excerpt: After a brief review of the puzzling light scalar meson sector of QCD, a brief summary will be given of a paper concerning radiative decays involving the light scalars. There, a simple vector meson dominance model is constructed in an initial attempt to relate a large number of the radiative decays involving a putative scalar nonet to each other. As an application it is illustrated why a0(980)-f0(980) mixing is not expected to greatly alter the f0/a0 production ratio for radiative [phi] decays.

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.
