Abstract
A study of the two-jet mass spectrum measured with the UA 2 calorimeter has revealed a signal from hadronic decays ofW andZ bosons above a large background. Production and decay properties of the signal have been measured. The combined production cross-section σ·B(W, Z → two jets) is 9.6±2.3 (stat.)±1.1 (syst.) nb, compared with an expectation of 5.8 nb calculated to order α 2s . A limit on the production cross-section of additional heavy vector bosons decaying into two jets is given as a function of the boson mass.

The PYTHIA event generator has been modified to allow for multiple interactions assuming a varying impact parameter and a hadronic matter overlap consistent with a double Gaussian matter distribution. The cross-section for this process has a continuous turnoff at 1.65 GeV. The list of PYTHIA parameters changed from their default values is: IPY(3)=12, IPY(12)=4, IPY(17)=3, PYPAR(32)=1.65
