Just a few days ago the CDF collaboration announced their new measurement of the W boson mass, with a considerable improvement over the precision of the current world average for that quantity. Now DZERO, the competitor experiment, has also published their own new measurement, which is based on a statistics of 4.3 inverse femtobarns - twice as many data as the ones used by CDF. read more
