How CMS weeds out particles that pile up
When the CMS experiment records particle collision events, a large number of unwanted extra collisions overlap in the detector and hide the rare particle collision that is worthwhile studying. CMS physicists have developed a new method that gives improved precision for the study of collisions even when occurring together with 50 or more extra interactions.

The LHC circulates protons inside its beam-pipes not in a continuous stream but in several very closely packed bunches.
