Recent Results on Intermediate Vector Boson Properties at the CERN Super Proton Synchrotron Collider
Phys. Lett. 166B (1986) 484; Eur. Lett. 1 (1986) 327;

Abstracts
The properties of a sample of 172 charged intermediate vector bosons decaying in the (e ν_e) channel and 16 neutral intermediate vector bosons decaying in the (e⁺ e^–) channel are summarized. Masses, decay widths, decay angular distributions, and production cross sections are given, and a limit is put on the number of light neutrino types N_ν < 10 at 90% CL.
