BBC: The CERN research teams that announced the detection of the Higgs particle last month have updated their findings. Because the theorized particle exists for only a brief period of time before decaying into other particles, the identity of the particle can be determined from the various ways that it decays. After examining two additional decay channels, the Atlas detector team has reported an increase in the statistical significance of the Higgs signal to 5.9 sigma. The CMS detector team members reiterated their 5-sigma signal after they included more of the data collected this year.
