A Test of QCD based on three jet events from Z0 decays

The L3 collaboration Adeva, B. ; Adriani, O. ; Aguilar-Benitez, M. ; et al.
Phys.Lett.B 263 (1991) 551-562, 1991.
Inspire Record 315954 DOI 10.17182/hepdata.38291

We present a study of 43 000 3-jet events from Z 0 boson decays. Both the measured jet energy distributions and the event orientation are reproduced by second order QCD. An alternative model with scalar gluons fails to describe the data.

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

The CDF collaboration Abe, F. ; Amidei, Dante E. ; Apollinari, G. ; et al.
Phys.Rev.Lett. 67 (1991) 1502-1506, 1991.
Inspire Record 317764 DOI 10.17182/hepdata.19899

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).

Determination of the relative branching ratios for p anti-p ---> pi+ pi- and p anti-p ---> K+ K-

The CPLEAR collaboration Adler, R. ; Angelopoulos, A. ; Apostolakis, A. ; et al.
Phys.Lett.B 267 (1991) 154-158, 1991.
Inspire Record 317491 DOI 10.17182/hepdata.48425

The ratio of the branching fractions for p p →K + K − and p p →π + π − was determined with the CPLEAR detector, by stopping antiprotons in a gaseous hydrogen target at 15 bar pressure. It was found to be BR(K + K − )/BR( π + π − )=0.205± 0.016. The fraction of P-wave annihilation at rest at this target density was deduced to be (38±9)%.
