The world's largest particle accelerator, the Large Hadron Collider, is back in action.

The LHC at CERN, outside of Geneva, is set to run 24/7 for nearly four years at a record energy of 13.6 trillion electronvolts

CERN used the LHC to discover the Higgs boson on July 4, 2012, LHC has circumference 27 KM 

LHC tools with greater precision and allow for more particle collisions, brighter light and more discovery about particles in quantum field theory.

In LHC hardon particale (lead, xenon and oxygen ions at different levels of the mass spectrum) in a way that forms two beams traveling in opposite directions

When two electrons interact, for example, they exchange particles of light or photons that are the "force carriers" of an electromagnetic interaction

Scientists hope to answers questions about the origin of the matter–antimatter asymmetry in the universe and search for candidates for dark matter.
