How wide is a Higgs?
25 Mar 2014: Jon Butterworth: In accord with Heisenberg’s uncertainty principle, short-lived particles have uncertain mass. So the Higgs boson, which gives mass to other particles, is uncertain about its own mass. New results from CMS at the CERN LHC have started to tell us how uncertain
