We have observed over 102 events of the type W→τν followed by τ→ hadrons, where the taus are identified by their decay into one or three charged particles. We measure the cross section times branching ratio for pp¯→W→τν and compare it to the value for W→eν to directly measure the ratio of weak coupling constants gτ/ge. We find gτ/ge=0.97±0.07, consistent with lepton universality.

The charge asymmetry of leptons from W-boson decay has been measured using p¯p data from the Collider Detector at Fermilab at √s =1.8 TeV. The observed asymmetry is well described by most of the available parton distributions.

Inclusive jet cross-section in anti-p p collisions at S**(1/2) = 1.8-TeV

The CDF collaboration Abe, F. ; Amidei, Dante E. ; Apollinari, G. ; et al.
Phys.Rev.Lett. 68 (1992) 1104-1108, 1992.
Inspire Record 319237 DOI 10.17182/hepdata.19883

We present a measurement of the inclusive jet cross section in p¯p collisions at √s =1.8 TeV at the Fermilab Tevatron using the Collider Detector at Fermilab. Good agreement is seen with the predictions of recent next-to-leading-order [O(αs3)] QCD predictions. The dependence of the cross section on clustering cone size is reported for the first time. An improved limit on Λc, a term characterizing possible quark substructure, is set at 1.4 TeV (95% C.L.).

We have measured the Z-boson production differential cross section as a function of transverse momentum using Z→ee and Z→μμ decays in p¯p collision at √s =1.8 TeV with the Collider Detector at Fermilab. Comparison with standard-model predictions shows good agreement over the range 0

Errors are systematic and statistical combined, and are correlated bin to bin due to the correction for resolution smearing.


A Determination of sin**2-theta from the forward - backward asymmetry in p anti-p ---> Z0 X ---> e+ e- X interactions at s**(1/2) = 1.8-TeV

An analysis of the forward-backward asymmetry in Z0 decays using data from the Collider Detector at Fermilab at √s =1.8 TeV yields AFB=[5.2±5.9(stat)±0.4(syst)]% and sin2θ¯W =0.228−0.015+0.017(stat)±0.002(syst).

Inspire Record 314225 DOI 10.17182/hepdata.19900

Using the Collider Detector at Fermilab, the W-boson differential cross section dσ/dPT is measured using W→eν events in proton-antiproton collisions at √s =1.8 TeV. A next-to-leading-order theoretical calculation agrees well with the data. The cross section (σ) for PT>50 GeV/c is measured to be 423±58(stat)±108(syst) pb.
