Abstract:

Data are presented on the reaction e+e- → γ + no other detected particle at centre-of-mass energies of 89.48, 91.26 and 93.08 GeV. The cross-section for this reaction is related directly to the number of light neutrino generations which couple to the Z0 boson, and to several other possible phenomena such as the production of excited neutrinos, the production of any invisible 'X' particle, and the magnetic moment of the tau neutrino. Based on the observed number of single photon events, the number of light neutrinos that couple to the Z0 is measured to be Nν = 2.89 ± 0.38. No evidence is found for anomalous production of energetic single photons, and upper limits at 95% confidence level are determined for excited neutrino production (BR < 4 - 8 × 10-6 depending on its mass), production of an invisible 'X' particle (σ < 0.1 pb for masses below 60 GeV), and the magnetic moment of the tau neutrino (< 5.1 × 10-6μB). © Springer-Verlag 1997.

Abstract:

An upper limit for BR(Z0 -»3g) is obtained from a correlation method, which distinguishes statistically between quark and gluon jets by using the difference in their charged particle multiplicity distributions. From the sample of threefold symmetric three-jet events collected by the DELPHI experiment at LEP during 1991-1994, the 95% confidence level upper limit is deduced to be: BR(Zn -> 3g) < 1.6 x 10~2 for the JADE and BR(Z0 -> 3g) < 1.5 x 10~2 for the DURHAM jet-finder.

Abstract:

Using data accumulated by DELPHI during the November 1995 LEP run at 130-136 GeV, searches have been made for events with jets or leptons in conjunction with missing momentum. The results are interpreted in terms of limits on the production of neutralinos, scalar leptons, and scalar quarks.
