Study of Z boson pair production in e+ e- interactions at s**(1/2) = 192-GeV - 202-GeV

The L3 collaboration Acciarri, M. ; Achard, P. ; Adriani, O. ; et al.

The cross section for the production of Z boson pairs is measured using the data collected by the L3 detector at LEP in 1999 in e^+e^- collisions at centre-of-mass energies ranging from 192 GeV up to 202 GeV. Events in all the visible final states are selected, measuring the cross section of this process. The special case of final states containing b quarks is also investigated. All results are in agreement with the Standard Model predictions.

A Measurement of the production of D*+- mesons on the Z0 resonance

The OPAL collaboration Akers, R. ; Alexander, G. ; Allison, John ; et al.
Z.Phys.C 67 (1995) 27-44, 1995.
Inspire Record 382219 DOI 10.17182/hepdata.48317

We have studied the production of D*± mesons in a sample of 1.25 million multihadronic decays of the Z0, in which 1969 candidates have been identified. We have determined the total multiplicity of charged D* mesons in multihadronic Z0 decays to be
