A couple of months back I wrote an article explaining intuitively why most types of particles decay. If you read that article you may be left wondering why a few types of particles, including the ones out of which we’re made, don’t decay. An answer to that question has now arrived, in the form of a new article:“Most Particles Decay – Yet Some Don’t!”. I hope you find it useful, and as always feel free to ask me to clarify points that don’t make sense to you.
From the CMS experiment at the Large Hadron collider, a proton-proton collision that created a Higgs boson, which subsequently decayed to two particles of light (shown as green rods.)
