K. Abe et al., COMPARISON OF A NEW CALCULATION OF ENERGY-ENERGY CORRELATIONS WITH E(-)-] HADRONS DATA AT THE Z(0) RESONANCE()E(), Physical review. D. Particles and fields, 52(7), 1995, pp. 4240-4244
We have compared a new QCD calculation by Clay and Ellis of energy-ene
rgy correlations (EEC's) and their asymmetry (AEEC's) in e(+)e(-) anni
hilation into hadrons with data collected by the SLD experiment at SLA
G. From fits of the new calculation, complete at O(alpha(s)(2)), we ob
tained alpha(s)(M(Z)(2)) = 0.1184 +/- 0.0031 (expt) +/- 0.0129 (theory
) (EEC) and alpha(s)(M(Z)(2)) = 0.1120 +/- 0.0034 (expt) +/- 0.0036 (t
heory) (AEEC). The EEC result is significantly lower than that obtaine
d from comparable fits using the O(alpha(s)(2)) calculation of Kunszt
and Nason.
