Some First Results from the Mark II at SPEAR. [Branching Ratio, Cross Sections]

Description: 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' ..-->.. ..gamma..eta'/sub c/(3455)) x BR(eta'/sub c/(3455 ..-->.. ..gamma..psi)). 10 references.

Results from the Mark II dectetor at SPEAR: SLAC-LBL Mark II collaboration

Description: Some recent results are presented from the Mark II detector at SPEAR: observation of some new D meson decay modes, including the Cabibbo suppressed K/sup -/K/sup +/ and ..pi../sup -/..pi../sup +/ modes, measurements of the rho ..nu.. and ..pi nu.. decays of the tau, and some new data on psi decays. 17 references.

Results on two-photon interactions from Mark II at SPEAR

Description: 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/sup +/e/sup -/ ..-->.. e/sup +/e/sup -/ eta' has been measured over the beam energy range from 2 to 4 GeV. The radiative width GAMMA/sub ..gamma gamma../(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 A/sub 2/(1310) and f'(1515) mesons ha… more

First results from Mark II at SPEAR

Description: First results from the SLAC-LBL Mark II magnetic detector at SPEAR are presented. The performance of the detector is discussed and preliminary results are given on inclusive baryon production R/sub p + anti p/, R/sub ..lambda.. + anti ..lambda../, on decay modes of the D mesons and on two-photon production of eta' mesons.
