How to make a Higgs boson

It doesn't seem like collisions of particles with no mass should be able to produce the "mass-giving" boson, the Higgs. But every other second at the LHC, they do. Einstein's most famous theory, often written as E=mc2, tells us that energy and matter are two sides of the same coin. The Large Hadron Collider uses this principle to convert the energy contained within ordinary particles into new particles that are difficult to find in nature--particles like the Higgs boson, which is so massive that...
