A Combination of Preliminary Electroweak Measurements and Constraints on the Standard Model
/ALEPH Collaboration ; DELPHI Collaboration ; L3 Collaboration ; OPAL Collaboration ; LEP Electroweak Working group
This note presents a combination of published and preliminary electroweak results from the four LEP collaborations ALEPH, DELPHI, L3 and OPAL based on electron-positron collision data taken at centre-of-mass energies above the Z-pole, 130 GeV to 209 GeV (LEP-II), as prepared for the 2006 summer conferences. Averages are derived for di-fermion cross sections and forward-backward asymmetries, photon-pair, W-pair, Z-pair, single-W and single-Z cross sections, electroweak gauge boson couplings, W mass and width and W decay branching ratios.

Search for Neutral MSSM Higgs Bosons at LEP ; rev. version
/ALEPH Collaboration ; DELPHI Collaboration ; L3 Collaboration ; OPAL Collaboration
The four LEP collaborations, ALEPH, DELPHI, L3 and OPAL, have searched for the neutral Higgs bosons which are predicted within the framework of the Minimal Supersymmetric Standard Model (MSSM). the data of the four collaborations are statistically combined and examined for their consistency with the background hypothesis and for a possible Higgs boson signal.

Test of color reconnection models in Z $\to$ 3 jets
/ Rudolph, G
Hadronic Z decays into three jets are used to test QCD models of color reconnection (CR). The sensitive quantity is the rate of gluon jets with a gap in rapidity and zero jet charge. [...]

A Combination of Preliminary Electroweak Measurements and Constraints on the Standard Model, 2004 ; long version
/ALEPH Collaboration ; DELPHI Collaboration ; L3 Collaboration ; OPAL Collaboration
This note presents a combination of published and preliminary electroweak results from the four LEP collaborations and the SLD collaboration which were prepared for the 2004 summer conferences. The main changes with respect to the experimental results presented in summer 2003 are updates to the W branching fractions and four-fermion cross sections measured at LEP-2, and the SLD/LEP heavy-flavour results measured at hhe Z pole..

Combination of the LEP II ffbar Results

Preliminary combinations of measurements of the 4 LEP collaborations of the process e+e- -> f\bar f at LEP-II are presented, using data from the full LEP-II data set where available. Cross-sections and forward-backward asymmetry measurements are combined for the full LEP-II data set. [...]
