"Datasets are the currency of physics. As data accumulate, measurement uncertainty ranges shrink, increasing the potential for discoveries and making non-observations more stringent, with more far-reaching consequences. In collider experiments, the amount of data is measured by the total number of collisions observed and the rate of those collisions, called the luminosity. In 2011, the Large Hadron Collider (LHC) produced more collisions than scientists dared to expect, breaking the world record luminosity in April and then continuing to grow seven-fold. By the end of the proton collision run in November, 240 million protons were colliding each second."

CMS Particle Detector
The LHC smashes groups of protons together and very close to the speed of light: 40 million times per second and with seven times the energy of the most powerful accelerators. When the collisions happens some of its energy is turned into mass and previously unobserved, short-lived particles – which could give clues about how Nature behaves at a fundamental level - fly out and into the detector.
