On July 31, the ATLAS collaboration presented further data analysis, including a third channel. They improved the significance to 5.9 sigma, and described it as an "observation of a new particle" with mass 126 ± 0.4 (stat.) ± 0.4 (sys) GeV/ c. Also CMS improved the significance to 5 sigma with the boson's mass at 125.3 ± 0.4 (stat) ± 0.5 (sys) GeV/ c.
