This diagram shows the layout for the LHCb detector, which is part of the LHC project at CERN. The main purpose of this detector is to look for rare decays of a heavy quark known as 'bottom,' a version of the down quark that is found in protons and neutrons. In particular, decays by a process known as 'CP violation' will be studied to investigate nature's preference for matter over antimatter.
