Four points to CMS
To make new discoveries in an accelerator, scientists can increase the energy and/or the luminosity (related to collision rate). Increased energy is pretty clear: the harder protons hit protons in the LHC, the more likely interesting things will come out. Luminosity is different. The greater the rate of collisions (luminosity), the more chances we have to create something new - and the more complicated the analysis. This CMS event has four different collisions at pretty much the same time. Count them!
