How the Higgs boson is born and how it dies: the most precise picture so far

Another of those “freak” research publications, which so befuddle the makers of university league tables, is on the way¹. Having made the best independent measurements they could with the data taken between 2010 and 2012, the ATLAS and CMS collaborations have now combined their results to produce the clearest picture so far of how the Higgs boson is produced, and how it decays.

The result is preliminary so far - though much detail is already publicly available. It follows a similar kind of combination of data pinning down the mass of the Higgs boson.
