It is difficult to detect the Higgs boson. The Higgs boson is very massive compared to other particles, so it does not last very long. There are usually no Higgs bosons around because it takes so much energy to make one. The Large Hadron Collider at CERN was built mainly for this reason. It speeds up two bunches of particles to almost light speed (travelling in opposite directions), before setting them on a path to collide with each other.
