A measurement of two-jet decays of theW andZ bosons at the CERN\(\bar p\)p collider
1991
A study of the two-jet
mass spectrummeasured with the UA 2 calorimeter has revealed a signal from hadronic decays ofW andZ
bosonsabove 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 s 2 . A limit on the production cross-section of additional heavy
vector bosonsdecaying into two jets is given as a function of the
bosonmass.
