AbstractAbstract
[en] Experimental evidence for the existence of the decay psi(3684) → γchi, chi → 4π/sup +-/, π+π-, K+K-, and also γpsi(3095) is presented. There is clear evidence for at least two chi states decaying to hadrons, one at 3.41 +- 0.01 GeV and the other at 3.53 +- 0.02 GeV. The chi(3410) decays into ππ and KK and thus must have even spin and parity. There is also evidence for one state decaying to psiγ at a mass of either 3.50 +- 0.01 GeV or 3.27 +- 0.01 GeV. The data, taken together, indicate the existence of at least three chi states

AbstractAbstract
[en] An analysis of data at the psi(3.7) resonance gives a partial width to electrons, MMA ub e/ = 2.2 +- 0.5 keV, and limits on total width 200 keV < MMA lt 0 keV. The decay psi(3.7) → psi(3.1)π+π- is observed with a branching ratio 0.31 +- 0.04, and psi(3.7) → psi(3.1) + anything has a branching ratio of 0.54 +- 0.08. The psi resonances appear to have the same G-parity. An enhancement occurs in the total hadronic cross section at a c.m. energy of about 4.1 GeV, rising to about 32 nb from a level of 18 nb adjacent to peak, which is about 300 MeV wide. The integrated cross section for the peak is about 5.5 nb-GeV, comparable to that for the psi(3.7) and psi(3.1) resonances. (U.S.)

AbstractAbstract
[en] Preliminary results on two-photon interactions from the SLAC-LBL Mark II magnetic detector at SPEAR are presented. The cross section for eta' production by the reaction e+e- → e+e- eta' has been measured over the beam energy range from 2 to 4 GeV. The radiative width GAMMA/sub γγ/(eta') has been determined to be 5.8 +- 1.1 keV (+- 20% systematic uncertainty). Upper limits on the radiative widths of the f(1270), and A2(1310) and f'(1515) mesons have been determined

AbstractAbstract
[en] Preliminary results are given from the Mark II experiment at SPEAR on radiative decays of the psi' (3684) and on inclusive baryon production from 3.67 to 7.4 GeV center-of-mass energy. A 90% confidence level upper limit of 0.12% is given for BR[psi' → γeta'/sub c/(3455)] x BR[eta'/sub c/(3455 → γpsi)]. 10 references
