LHC is back with big energy boost

The Large Hadron Collider (LHC) is operating again after its winter break. Early on Thursday, opposing stable beams of protons were smashed into each other at four observation positions. The total collision energy in these bunches of sub-atomic particles was eight trillion electron volts - a world record. Scientists expect the big boost in capability to significantly increase the collider's chances of discovering "new physics". The great expectation is that they will definitively confirm or deny the existence of the Higgs boson, the elusive particle that would help explain why matter has mass. for the full news follow the link http://www.bbc.co.uk/news/science-environment-17625123
