A Higgs boson Q&A

A Higgs boson Q&A:





From the excellent "The Higgs Boson (God Particle) Explained" video





Last week's announcement of the discovery of a new particle seemed to answer one of the great outstanding questions in physics. But for those who haven't been immersed in all things LHC, the results were likely to raise all sorts of new questions (along with "what was all the fuss about again?"). So, to help navigate the post-Higgs world, we put together a short Q&A, based on questions that some of the Ars staff had.
I know we detected it in the Large Hadron Collider, but how did they actually make Higgs bosons?
There are two ways to answer that question. The first is that we're simply converting energy into matter. The protons in the collider carry a tremendous amount of energy, and it has to go somewhere. Given Einstein's E = mc2, we know that some of that energy can be converted into matter. That's why things that are much heavier than two protons at rest can pop out of the collisions.
