Abstract:

The production of neutral K*(890) and ρ0 mesons was studied in e+e- annihilation at s=29 GeV using the High Resolution Spectrometer at PEP. Differential cross sections are presented as a function of the scaled energy variable z and compared to π0 and K0 production. The measured multiplicities are 0.84±0.08 ρ{variant}0 mesons and 0.57±0.09 K*0(890) mesons per event for a meson momentum greater than 725 MeV/c. The ratios of vector meson to pseudoscalar meson production for (u,d), s and c quark are compared to predictions of the Lund model. © 1985.

Abstract:

A search was made for e⁺e^-→X1X2 where X1 consists of one or more light unobservable particles and X2 decays promptly to a visible jet of particles. One event was found for an integrated luminosity of 176 pb^-1, a rate consistent with known backgrounds. This result places a significant constraint on a number of theoretical models. © 1985.

Abstract:

From an integrated luminosity of ∫Ldt = 116 nb-1, 10events are found which contain an electron pair of mass in the range 12 < Mee < 26 GeV c2 and electron transverse momenta pTe > 5 GeV c. THe sample are described, as well as some featruyres of the The production characteristics of this sample are described, as well as some features of the estimated to be 2.2±0.6 events. The production characteristics of this sample are described, as well as some features of the associated event topology. Comparisons are made with the expectations for such electron pair production from the Drell-Yan mechanism and from the semi-leptonic decay of heavy flavours. © 1985.
