International team of LHC and Tevatron scientists announces first joint result

Scientists working on the world's leading particle collider experiments have joined forces, combined their data and produced the first joint result from Fermilab's Tevatron and CERN's Large Hadron Collider (LHC), past and current holders of the record for most powerful particle collider on Earth. Scientists from the four experiments involved -- ATLAS, CDF, CMS and DZero -- announced their joint findings on the mass of the top quark today at the Rencontres de Moriond international physics confere...
