We have studied measurements of the cross section for e+e- --> hadrons for center-of-mass energies in the range 20--209 GeV. We find an apparent excess over the predictions of the Standard Model across the whole range amounting to more than 4\sigma. As an example, we compare the data to predictions for a light scalar down-type quark which fit the excess well. 
Closing the light sbottom mass window from a compilation of e + e ! hadron data
Abstract The e + e − →hadron cross section data from PEP, PETRA, TRISTAN, SLC and LEP, at centre-of-mass energies between 20 to 209 GeV, are analysed to search for the production of a pair of light
The light sbottom mass window revisited
An apparent excess of more than 4σ in the e+e− → hadron cross section for centre-of-mass energies between 20 to 209 GeV has recently been reported. This excess was found to be well reproduced over


Low-energy supersymmetry and the Tevatron bottom-quark cross section.
It is shown that pair production of light gluinos, of mass 12 to 16 GeV, with two-body decays into bottom quarks and light bottom squarks, yields a bottom-quark production rate in agreement with hadron collider data.
A Compilation of total cross-section data on e+ e- ---> hadrons and pQCD tests
All available data on the total cross sections and R-ratio of e + e − → hadrons are compiled from the PPDS (DataGuide), PPDS (ReacData) and HEPDATA (Reaction) databases and transformed to a
Light gluino and the running ofαs
A gluino in the mass range 12--16 GeV combined with a light (2--5.5 GeV) bottom squark, as has been proposed recently to explain an excess of b quark hadroproduction, would affect the momentum-scale
Theoretical precision in estimates of the hadronic contributions to (g − 2)μ and αQED(Mz)
Abstract I review recent estimates of the non-perturbative hadronic vacuum polarization contributions. Since these at present can only be evaluated in terms of experimental data of limited precision,
Two-Fermion Production in Electron-Positron Collisions
This report summarizes the results of the two-fermion working group of the LEP2-MC workshop, held at CERN from 1999 to 2000. Recent developments in the theoretical calculations of the two fermion
Standard Model Physics Results from LEP2
At LEP2 many Standard Model predictions are tested up to centreof-mass energies of 209 GeV . Fermion pair production cross sections and asymmetries agree well with the theoretical expectation over
Combination procedure for the precise determination of Z boson parameters from results of the LEP experiments
The precise determination of the Z boson parameters from the measurements at the Z resonance by the four collaborations ALEPH, DELPHI, L3 and OPAL in e+e- collisions at the large electron positron
Determination of the QCD coupling αs
Theoretical basics and experimental determinations of the coupling parameter of the strong interaction, αs, are reviewed. The world average value of αs, expressed at the energy scale of the rest mass
Do electroweak precision data and Higgs-mass constraints rule out a scalar bottom quark with mass of order 5 GeV?
It is shown that a light sbottom cannot be ruled out by electroweak precision data and the bound on the lightest CP-even Higgs-boson mass is the same as the mass bound m(h) less, similar 123 GeV.
ZFITTER v.6.21: A semi-analytical program for fermion pair production in e+e- annihilation
We describe ZFITTER, a Fortran program based on a semi-analytical approach to fermion pair production in e+e− annihilation at a wide range of centre-of-mass energies, including the PETRA, TRISTAN,
