This is a compilation of measurements of the weak mixing angle. The new Tevatron combined result of sin2θefflept=0.23148 ± 0.00033 rivals the precision of the two previous measurements by the LEP-1 experiments at CERN and SLD at SLAC, and it lies midway between them. The Tevatron combination agrees very well with the world average of all results shown by the shaded band.
