How massive detectors at CERN search for tiny particles

The Large Hadron Collider (LHC) at CERN is the largest and most powerful particle accelerator in the world. Beams of high-energy particles are collided head-on inside massive, complex detectors at four points around the 27-km machine. This lecture provides a peek inside the LHC collider and experiments, how they work, and how physicists can use the data to identify and study new particles like the Higgs boson.
