We report on the measurement of the leptonic and hadronic cross sections and leptonic forward-backward asymmetries at theZ peak with the L3 detector at LEP. The total luminosity of 40.8 pb−1 collected
Results from 1990 data. Additional systematic uncertainty of 0.4 pct.. Efficiency corrected cross section for both leptons inside the angular range 44 to 136 degrees with an acollinearity cut of < 25 degrees.
Results from 1991 data. Additional systematic uncertainty of 0.3 pct.. Efficiency corrected cross section for both leptons inside the angular range 44 to 136 degrees with an acollinearity cut of < 25 degrees.
Results from 1992 data. Additional systematic uncertainty of 0.3 pct.. Efficiency corrected cross section for both leptons inside the angular range 44 to 136 degrees with an acollinearity cut of < 25 degrees.
